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
backgroundFortification of human milk is necessary for preterm infant growth. We evaluated the impact of an acidified human milk fortifier and nonacidified human milk fortifiers on growth velocity in preterm infants.
methodsThis retrospective, single-center study compared preterm infants (N = 375) receiving either acidified human milk fortifier (n = 163) or a combination of standard-protein and high-protein human milk fortifier (n = 212) in a tertiary neonatal intensive care unit. Infants with a birth weight of 500-1800 g and feeding initiation by day of life 7 were eligible for inclusion. The coprimary outcome was weight velocity (g/kg/day) at day of life 28 and 36 weeks' postmenstrual age. Multivariable linear regression model for the coprimary outcomes and growth-related secondary outcomes were adjusted for gestational age, birth weight, sex, and race.
resultsInfants receiving standard-protein/high-protein human milk fortifiers demonstrated higher weight velocity at day of life 28 (12.09 ± 3.27 vs 10.92 ± 3.06 g/kg/day, P < 0.001) and 36 weeks' postmenstrual age (13.31 ± 2.23 vs 12.67 ± 2.28 g/kg/day, P = 0.02) compared with those receiving acidified human milk fortifier. Length velocity at day of life 28 was greater in the standard-protein/high-protein group (1.09 ± 0.54 vs 0.97 ± 0.43 cm/week, P = 0.02) but not at 36 weeks' postmenstrual age (P = 0.06). Human milk exposure and incidence of comorbidities were similar between groups.
conclusionsStandard- and high-protein human milk fortifiers were associated with improved weight and length growth in preterm infants.
