Comparison of Blood NLR and PLR Values Between Pregnant Women Diagnosed with Intrauterine Death (IUEX) After 20 Weeks and a Healthy Control Group

AbstractAim: The aim of this study is to compare NLR and PLR ratios between pregnant women diagnosed with intrauterine fetal death after 20 weeks and a healthy control group of pregnant women.Materials and Methods: This was a retrospective, single-center study that included 180 patients, comprising 90 pregnant women diagnosed with intrauterine death after 20 weeks and an equal number of healthy controls. NLR (NLR = neutrophil/lymphocyte) and PLR (PLR = platelet/lymphocyte) were calculated. Data distribution was compared using the Mann–Whitney U test when not normally distributed. ROC analysis was used to calculate cutoff points for NLR and PLR predicting IUEX.Results: Both NLR and PLR were significantly lower in the IUEX group compared with controls (NLR: p=0.020; PLR: p
