WeChat-Based Nursing Interventions in Women's Mobile Health: Systematic Review.

The review combined many different women's conditions, interventions, and outcomes, so it cannot identify which component worked or how well any single condition was supported. Most studies were conducted in China and many were published in Chinese, so the results may not transfer to other health systems or languages. Blinding participants and personnel was usually not feasible, and outcome assessors were not blinded, so self-reported outcomes may be biased. Outcome measurement and selective reporting were rated high risk across studies, and the overall evidence strength was low. The synthesis was narrative rather than pooled, because heterogeneity made meta-analysis inappropriate. Many studies combined multiple WeChat components, so the contribution of any single component cannot be separated.

Do not read this review as proof that WeChat nursing interventions work for women. Most included studies had high risk of bias, no blinding, and the review itself rated the evidence as low, so the findings are promising but not definitive.
