The results revealed that L-arginine was more effective in reducing the incidence of PE than placebo [odds ratio (OR)=0.36, 95% confidence interval (CI): 0.17, 0.77]. Also, the results showed no statistically significant difference between the two groups in systolic blood pressure (SBP; standard mean difference (SMD): -0.35, 95% CI: -91, 21) and diastolic blood pressure (DBP; SMD: -0.50, 95% CI: -1.08, 0.07). There was a statistically significant difference in neonatal birth weight between the two groups (SMD: -0.16, 95% CI: -31, -0.01). No statistically significant difference existed between the two groups in terms of gestational age (SMD: 0.6, 95% CI: -0.06, 0.18). Furthermore, there was no significant difference between the two groups in the APGAR score at one minute (SMD: 0.40, 95% CI: -0.02, 0.82). Our findings revealed that L-arginine supplementation during pregnancy reduced the incidence of PE in high-risk pregnancies. However, it does not significantly improve maternal and neonatal outcomes.</p>","PeriodicalId":14080,"journal":{"name":"International Journal of Fertility & Sterility","volume":"18 4","pages":"323-328"},"PeriodicalIF":2.3,"publicationDate":"2024-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11589976/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142675788","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
