1 · What the graph read from it

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.

2 · The registry

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

Edematous severe childhood malnutrition is distinct from the non-edematous form of malnutrition and remains a major cause of under-five mortality. Its etiology remains unclear, although aberrant one-carbon metabolism has emerged as a potential contributor. Here, we assess genetic variants at loci known to influence one-carbon metabolism, and determine their association with edematous malnutrition in Jamaica and Malawi. Six loci show evidence of association, including four related to homocysteine and folate metabolism - AHCYL1, PRICKLE2, GABBR2, and PLD2, with SNPs at the latter three also having direct effects on homocysteine-related metabolites in Mendelian Randomization. Collectively, one-carbon metabolism-related variants were significantly associated with edematous malnutrition (z = 3.2), with population differences linked to a shared East African genetic ancestry and distinct signatures of selection. These findings strengthen evidence implicating aberrant one-carbon metabolism in edematous malnutrition and highlight the utility of cell-free DNA, intra-continental admixture, and population genetics for mapping disease risk.
