Does fetal or maternal leap-2 level affect infant birth weight?
Article in BMC pregnancy and childbirth, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionThe etiology of maternal and infant weight gain during pregnancy is multifactorial. Many different biomarkers have been studied to elucidate this complex issue. Recent studies have led to the idea that Leap-2, which is thought to have an active role in energy metabolism, may also have an influence on infant birth weight. Therefore, we aimed to evaluate the relationship between Leap-2 levels and infant birth weight.
methodsIn this prospective study, we evaluated 102 patients with pregnancies of 34 weeks or more. Among those group, Leap-2 levels collected from maternal venous blood just before delivery and from umbilical cord during delivery. Accordingly, infant birth weights were recorded and analyzed in relation to Leap-2 concentrations.
resultsAs a result; Fetomaternal Leap-2 levels were correlated each other significiantly for the first time in the literature (p < 0.001, r = 0.611). In the analysis performed by categorizing maternal Leap-2 and infant birth weights with a 100 g and 150 g difference separately, statistically significant cut-off values were identified for infants born weighing over 3250 g.
conclusionsThese findings suggest that maternal Leap-2 levels which can potentially serve as a biomarker for birth weight prediction, may influence fetal growth even in normal pregnancies.
