Abstract:
Introduction: The efficacy of enoxaparin for recurrent abortion remains controversial. We conduct a systematic review and meta-analysis to explore the influence of enoxaparin versus placebo on recurrent abortion.Methods: We search PubMed, Embase, Web of Science, EBSCO, and Cochrane Library databases through February 2019 for randomized controlled trials (RCTs) assessing the effect of enoxaparin versus placebo on recurrent abortion. This meta-analysis is performed using the fixed or random-effect model when appropriate.Results: Six RCTs involving 1034 patients are included in the meta-analysis. Overall, compared with control group for patients with recurrent abortion, enoxaparin has no obvious impact on live births (RR = 1.06; 95% CI = 0.97-1.16; p = .17), abortion rate (RR = 0.71; 95% CI = 0.45-1.10; p = .13), birth weight (std. MD = 0.38; 95% CI = -0.21-0.96; p = .21), preterm delivery (RR = 0.55; 95% CI = 0.30-1.00; p = .05), preeclampsia (RR = 1.52; 95% CI = 0.42-5.51; p = .52), and postpartum hemorrhage (RR = 1.17; 95% CI = 0.69-1.99; p = .55).Conclusions: Enoxaparin may provide no significant benefits to patients with recurrent abortion.
