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
Infant formula (IF) is essential when breastfeeding is not possible or sufficient. We previously reported that, in a randomized, double-blind clinical trial with 180 healthy infants, an A2 β-casein IF containing high sn-2 palmitate levels, and casein phosphopeptides (CPP) improved stool consistency, gastrointestinal comfort, crying time, and bone mineral density. Here, we present complementary, pre-specified, biochemical analyses from the same cohort. Relative to standard cow's milk IF, the A2 β-casein, high sn-2 palmitate and CPP IF reduced fatty acid and calcium excretion, reduced calcium fatty acid soap formation, increased hair iron and zinc content, and was associated with lower cortisol levels. These parameters were not different from the breastfed group in the study. Together, the previously published clinical outcomes and the biochemical findings presented here suggest that an IF designed to narrow the compositional gap with human milk may deliver some of the advantages of breastfeeding, providing a path for improving IF compositions.
