Background: Spontaneous abortion is the spontaneous loss of the fetus before the 20th week of gestation. One out of four of identified pregnancies end in abortion, resulting in a frequent first trimester complication. The neutrophil-lymphocyte ratio (NLR) emerges as a possible prognostic marker in view of its usefulness in other inflammatory diseases. Recent studies have confirmed its association in patients with and without threatened abortion, however there are still studies that do not establish an association. Objective: To assess whether there is an association between a higher NLR value and a higher probability of spontaneous abortion in pregnant women with and without threatened abortion. Material and methods: A systematic search for cases and controls and cohorts was carried out in PubMed, Scopus, Medline, Embase, Google Scholar, and Web of Science until August 2020. NLR means were evaluated in all cases. Subgroup analysis was used to assess causes of heterogeneity. The Newcastle Ottawa scale and Egger's test were applied to assess biases. Revman 5.2 and Stata 14 were used for the analysis. Results: Ten studies were obtained for the meta-analysis. The Odds Ratio (OR) was not significant despite favoring the occurrence of abortion (OR = 0.83; IC 95% = 0.55, 1.26). High heterogeneity was found (I2 = 88%) and the Egger test ruled out the effect of small studies (p = 0.812). Conclusions: There is no association between the NLR value and a higher probability of a spontaneous abortion outcome in pregnant women with or without threat of abortion.
