Herbal medicine (Hyeolbuchukeo-tang or Xuefu Zhuyu decoction) for treating primary dysmenorrhoea: protocol for a systematic review of randomised controlled trials.
Primary dysmenorrhoea is menstrual pain without pelvic pathology and is the most common gynaecological condition in women. Xuefu Zhuyudecoction (XZD) or Hyeolbuchukeo-tang, a traditional herbal formula, has been used as a treatment for primary dysmenorrhoea. The purpose of this study is to assess the current published evidence regarding XZD as treatment for primary dysmenorrhoea.
The following databases will be searched from their inception until April 2017: MEDLINE (via PubMed), Allied and Complementary Medicine Database (AMED), EMBASE, The Cochrane Library, six Korean medical databases (Korean Studies Information Service System, DBPia, Oriental Medicine Advanced Searching Integrated System, Research Information Service System, Korea Med and the Korean Traditional Knowledge Portal), three Chinese medical databases (China National Knowledge Infrastructure (CNKI), Wan Fang Database and Chinese Scientific Journals Database (VIP)) and one Japanese medical database (CiNii). Randomised clinical trials (RCTs) that will be included in this systematic review comprise those that used XZD or modified XZD. The control groups in the RCTs include no treatment, placebo, conventional medication or other treatments. Trials testing XZD as an adjunct to other treatments and studies where the control group received the same treatment as the intervention group will be also included. Data extraction and risk of bias assessments will be performed by two independent reviewers. The risk of bias will be assessed with the Cochrane risk of bias tool. All statistical analyses will be conducted using Review Manager software (RevMan V.5.3.0).
This systematic review will be published in a peer-reviewed journal. The review will also be disseminated electronically and in print. The review will benefit patients and practitioners in the fields of traditional and conventional medicine.

Chinese herbal formula siwutang for treating primary dysmenorrhea: A systematic review and meta-analysis of randomized controlled trials.
Primary dysmenorrhea (PD) is a common gynecological disorder that usually begins in adolescence, and affects patients' daily activities and quality of life. Non-steroidal anti-inflammatory drugs (NSAIDS) are considered the first-line treatment, and hormonal contraceptives are also recommended for PD, but both are prone to side-effects. The Chinese herbal formula Siwutang (SWT) and its derivative formulas are a common treatment for PD in China. This review assessed the efficacy and safety of SWT for the treatment of PD.
PubMed, EmBase, Cochrane CENTRAL, CNKI, Wanfang and CBM were searched. We included randomized controlled trials (RCTs) that investigated SWT for PD, compared with no intervention, placebo, or conventional Western medicine. The outcome measurements included pain intensity measured by visual analogue scale (VAS) or other validated scales, the Cox Menstrual Symptom Scale (CMSS), quality of life, response rate and adverse events. The Cochrane Collaboration's tool was used to assess the risk of bias. RevMan V.5.3 was used for data synthesis and meta-analysis. Risk ratio (RR) with 95 % confidence intervals (CIs) or mean difference (MD) with 95 % CIs was calculated for dichotomous data or continuous data, respectively. Heterogeneity among studies was evaluated using both a chi-square test and an I2 test.
A total of 38 RCTs involving 3982 participants were identified. The methodological quality of the included trials was generally poor. Moreover, the results for SWT compared with placebo were unclear, as there was only 1 RCT. SWT improved pain intensity measured by VAS (3 RCTs, n = 220, MD:-2.61, 95 % CI:-3.72 to -1.51) when compared with conventional medicine, and these results were statistically significant. The meta-analysis showed the superior effect of SWT (including derivative formulas) on response rate (35 RCTs, n = 3,695, RR: 1.28, 95 % CI: 1.22-1.34) with medium heterogeneity (I2 = 48 %). Both original SWT and its derivative formula XFSWT had a higher response rate than conventional medicine (23 RCTs, n = 2,493, RR: 1.28, 95 % CI: 1.23-1.33) (11 RCTs, n = 1,076, RR: 1.36, 95 % CI: 1.20-1.53). These results were statistically significant. No trial reported on quality of life or CMSS. Adverse events were reported by 5 studies, and meta-analysis showed SWT may be safer than conventional medicine in terms of the incidence of adverse events (3 RCTs, n = 236, RR: 0.17, 95 % CI: 0.07-0.38, I2 = 0%).
In conclusion, the included trials showed favorable effects of SWT for treating primary dysmenorrhea when compared with conventional medicine. SWT may be safer than conventional medicine, but insufficient data was reported. The level of evidence is low because of the high risk of bias. Thus, further well-designed clinical trials with large sample sizes are warranted.

Herbal medicine (Shaofu Zhuyu decoction) for treating primary dysmenorrhea: A systematic review of randomized clinical trials.
Shaofu Zhuyu decoction (SFZY) or Sobokchugeo-tang, a traditional herbal formula, is used as a treatment for primary dysmenorrhea. We searched four English, seven Korean, three Chinese, and one Japanese database from inception through January 2016 without a language restriction. All randomized controlled trials (RCTs) of SFZY or modified SFZY (MSFZY) were included. Data extraction and risk of bias assessments were performed by two independent reviewers. A total of 51 potentially relevant studies were identified, and 9 RCTs met our inclusion criteria. Seven RCTs tested the effects of SFZY or modified SFZY in treating dysmenorrhea. Three RCTs showed superior effects of (M)SFZY on the response rate, while the other three RCTs failed to do so (n=531, RR: 1.17, 95% CI: 1.09 to 1.26, P<0.0001, I(2)=0%). Three RCTs showed favorable effects of MSFZY for pain reduction compared with conventional drugs (n=340, SMD: -1.39, 95% CI: -2.23 to -0.55, P=0.01). Two RCTs examined the effects of modified SFZY plus conventional drugs and conventional drugs alone. The meta-analysis showed favorable effects of MSFZY (n=206; RR, 1.12; 95% CI 1.08 to 1.36; P=0.0009, I(2)=0%). Our systemic review and meta-analysis provide suggestive evidence of the superiority of SFZY over conventional drugs for treating primary dysmenorrhea. However, the level of evidence is low because of a high risk of bias.

Herbal medicine (Taohong Siwu Tang) for the treatment of primary dysmenorrhea: A systematic review and meta-analysis.
This systematic review aimed to evaluate the efficacy and safety of Tao-Hong Siwu Tang (TST) for the treatment of primary dysmenorrhea.
We searched four English databases (MEDLINE, EMBASE, Allied and Complementary Medicine Database, and Cochrane Central Register of Controlled Trials [CENTRAL, Cochrane Library]), three Chinese databases (China National Knowledge Infrastructure, Wanfang, and Chinese Science and Technology Periodical Database), two Korean databases (Oriental Medicine Advanced Searching Integrated System and Korean traditional Knowledge Portal), and one Japanese database (Citation Information by NII). All randomized controlled trials (RCTs) using TST or modified TST (MTST) were included. Three independent reviewers extracted the data, assessed the risk of bias according to the Cochrane criteria, and performed a meta-analysis.
A total of 85 possibly relevant articles were identified, and five trials met our inclusion criteria. The meta-analysis showed a favorable effect of MTST compared to non-steroidal anti-inflammatory drugs (NSAIDs) (n = 486, risk ratio [RR] = 1.53, 95% confidence interval [95% CI] = 1.37-1.72, I2 = 39%). Among the included trials, one RCT showed superior effects of MTST on primary dysmenorrhea recurrence rate compared to NSAIDs (n = 246, RR = 0.31, 95% CI = 0.15-0.63, P = 0.001). Another RCT revealed a beneficial impact of oral contraceptives (OCs) used in combination with TST compared to OCs alone (n = 60, RR = 1.35, 95% CI = 1.02-1.79, P = 0.04).
This systematic review and meta-analysis provides moderate quality evidence for the superiority of MTST over NSAIDs as well as that of TST plus OCs over OCs in the treatment of primary dysmenorrhea.
