What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Although maternal inflammation is increasingly recognized in the pathogenesis of preterm birth, evidence regarding the combined predictive value of platelet-to-lymphocyte ratio (PLR) and maternal serum ferritin levels remains scarce. The aim of this study was to evaluate the association and predictive performance of PLR and maternal serum ferritin levels, two readily available inflammatory biomarkers, with the incidence of preterm birth. A prospective cohort study was conducted. Pregnant women with singleton pregnancies between 28 and 36 weeks 6 days of gestation were consecutively recruited and followed until delivery. PLR was calculated from absolute platelet and lymphocyte counts obtained from complete blood count analysis, while maternal serum ferritin levels were measured using electrochemiluminescence immunoassay. The present study found that higher PLR (odds ratio (OR): 1.013; 95%CI: 1.002-1.025;
