Clinical Studies

Clinical trials for miscarriage

Up to 2012, nearly 600 clinical trials of Chinese herbal medicines for threatened miscarriage were identified from literatures. 65 commentary and 67 review articles were excluded. 187 duplicated publications were also excluded. Full texts of remained 272 clinical studies were assessed but 240 studies were further excluded, because mostly adverse effects of Chinese medicines were not reported as an outcome. At the end, 32 clinical studies with full records on the adverse effects of Chinese medicines for threatened miscarriage were available for quantitative and qualitative analysis.
