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 placenta plays influential role in the fetal development of mammals. But how the metabolic need of the fetal organs is related to that of the placenta, and whether this relationship is influenced by the sex of the fetus remain poorly understood.
objectivesThis study used pigs to investigate metabolomic signatures of male and female fetal organs, and determine the relevance of gene expression of the placenta and brain to the metabolism of peripheral organs.
methodsUntargeted metabolomics analysis was performed with the day-45 placenta, kidney, heart, liver, lung and brain of male and female pig fetuses to model sex differences in the metabolism of the peripheral organs relative to that of the brain and placenta. Transcriptomic analysis was performed to investigate the expression of metabolic genes in the placenta and fetal brain of both sexes.
resultsThe results of this study show that the fetoplacental metabolic regulation was not only influenced by the fetal sex but also dependent on the metabolic requirement of the individual organs of the fetus. Neural network modeling of metabolomics data revealed differential relationship of the metabolic changes of the peripheral organs with the placenta and fetal brain between males and females. RNA sequencing further showed that genes associated with the metabolism of the peripheral organs were differentially expressed in the placenta and fetal brain.
conclusionThe findings of this study suggest a regulatory role of the fetal brain and placenta axis in the sex-bias metabolism of the peripheral organs.
