Metabolic and Lactation Effects of Rumen-Protected Choline Supplementation in Peripartum Dairy Cows and Its Effects on Calf Growth Until Weaning.
Article in Metabolites, 2026. 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
backgroundThis study evaluated the effects of rumen-protected choline (RUPCHOL) supplementation in dairy cows from 21 days before calving to 28 days postpartum. The objective was to determine how RUPCHOL influences metabolic status, milk composition, and subsequent calf growth until weaning.
methodsTwenty-seven pregnant Holstein cows were assigned to a Control group (
resultsRUPCHOL supplementation tended to reduce serum aspartate aminotransferase and lowered concentrations of non-esterified fatty acids and β-hydroxybutyrate, indicating improved metabolic status. Milk total solids, fat, and protein percentages were higher in RUPCHOL-fed cows, suggesting enhanced milk quality. Maternal supplementation did not affect colostrum immunoglobulin G (IgG) content or calf body weight and body measurements (heart girth, wither height, hip height, and body length) from birth to weaning.
conclusionsIn summary, RUPCHOL supplementation improved indicators of metabolic health and milk composition of dairy cows during the peripartum period without altering calf growth outcomes.
