Fetal Huanjiang mini-pigs exhibit differences in nutrient composition according to body weight and gestational period.
Article in PloS one, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Low birth weight may negatively affect energy storage and nutrient metabolism, and impair fetal growth and development. We analyzed effects of body weight (BW) and gestational period on nutrient composition in fetal Huanjiang mini-pigs. Fetuses with the lowest BW (LBW), middle BW (MBW), and highest BW (HBW) were collected at days 45, 75, and 110 of gestation. Crude protein (CP), crude fat, amino acid (AA), and fatty acid (FA) concentrations were determined. The BW gain, carcass weight, fat percentage, and uterus weight of sows increased as gestation progressed, as did litter weight, average individual fetal weight, fetal body weight, and dry matter (DM). The concentrations of Ala, Arg, crude fat, Gly, Pro, Tyr, C14:0, C16:0, C16:1, C18:1n9c, C18:2n6c, C18:3n3, C18:3n6, C20:0, C20:3n6, saturated FA (SFA), and monounsaturated FA (MUFA) increased significantly as gestation progressed. The percentage of skeleton, and the ratio of the liver, lung, and stomach to BW decreased as gestation progressed. There were also significant reductions in the concentrations of CP, Asp, Glu, His, Ile, Leu, Lys, Phe, Ser, Thr, essential AA (EAA), acidic AA, C17:0, C20:4n6, C22:6n3, unsaturated FA (UFA), polyunsaturated FA (PUFA), n-3PUFA, n-6PUFA as gestation progressed, and reductions in EAA/total AA (TAA), PUFA/SFA, and n-3/n-6 PUFA. The LBW fetuses exhibited the lowest BW and crude fat, C14:0, C16:1, C17:0, C18:2n6c, and MUFA concentrations at days 75 and 110 of gestation. They also exhibited lower Tyr concentration at day 45 of gestation and lower Glu concentration at day 75 of gestation than HBW fetuses. These findings suggest that LBW fetuses exhibit lower amounts of crude fat and several FAs during mid-gestation and late-gestation, which may in turn affect adaptability, growth, and development.
