There was no significant difference in the IL‐18 levels in PE patients compared with controls. However, IFN‐γ was found to be significantly higher in women with PE than that in normotensive pregnant women (standardized mean difference = 0.93; 95% confident interval: 0.07, 1.79). Furthermore, stratification by specimen type, quality score, method of estimation of mean and standard deviation, and whether sampling not in labor/premature rupture of membrane/infection also showed significant differences in standardized mean difference of IL‐18, as well as IFN‐γ.</p> </sec> <sec id="aji12298-sec-0004" sec-type="section"> <title>Conclusion</title> <p>This meta‐analysis suggests that circulating higher IFN‐γ levels may be associated with preeclampsia.</p> </sec> </abstract>
