Effects of feeding infant formula rich in sn-2 palmitate for 6 months on fecal saponified fatty acids, calcium and stool characteristics: a cluster-randomized controlled trial.
Trial report in Nutrition journal, 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
backgroundHuman milk palmitic acid (PA) is mainly esterified at the sn-2 position of triacylglycerols, while infant formula contains palmitate predominantly in the sn-1/3 positions. Current evidence on long-term health effects of increasing sn-2 palmitate in formula remains insufficient. This study investigated the effects of high sn-2 PA formula (> 40%) on fecal saponified fatty acid, calcium, magnesium and stool characteristics in healthy full-term infants.
methodsIn this cluster-randomized controlled trial, healthy infants < 14 d were assigned to breastfeeding (BF group, n = 66), high sn-2 palmitate formula (sn-2 group, n = 66, 46.3% sn-2 PA) or low sn-2 palmitate formula (control group, n = 67, 10.3% sn-2 PA). Infant demographics, feeding status, stool characteristics, physical exams, and stool samples were collected at 6, 16, and 24 weeks. Per-protocol analysis was used.
resultsThe sn-2 group exhibited a significant time-dependent decline in fecal saponified PA and calcium over time (P
conclusionInfant formula enriched with > 40% sn-2 palmitate reduces fecal fatty acid and calcium excretion, supports efficient lipid and calcium absorption, shows a fecal magnesium pattern similar to breastfed infants, but does not alter stool characteristics relative to the control formula.
