Donor human milk storage and gastrointestinal morbidities in preterm infants: A case-control study.
Article in JPEN. Journal of parenteral and enteral nutrition, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundProlonged storage of donor human milk may alter its bioactive components, potentially affecting preterm infant outcomes. No prior studies have examined the impact of donor human milk storage duration on necrotizing enterocolitis or spontaneous intestinal perforation.
methodsIn a retrospective case-control study (February 2022 to January 2024) at a single neonatal intensive care unit, we evaluated preterm infants (<32 weeks' gestational age or birth weight <1700 g) receiving donor human milk. Cases (n = 36) had necrotizing enterocolitis (Bell stage ≥2A) or spontaneous intestinal perforation; controls (n = 226) were disease free. Donor human milk storage duration (days from expression to consumption) was calculated using lot expiration dates. Logistic regression assessed associations, adjusting for gestational age, birth weight, and other confounders.
resultsOf 262 infants, 36 developed necrotizing enterocolitis (n = 28) or spontaneous intestinal perforation (n = 8). Mean donor human milk storage duration was 258.6 (SD, 29.9) days in cases and 244.5 (SD, 21.7) days in controls (P = 0.01). Each additional storage day increased the adjusted odds of necrotizing enterocolitis or spontaneous intestinal perforation by 3.6% (95% confidence interval, 1.17-5.5; P < 0.001), after accounting for maternal and infant comorbidities.
conclusionsProlonged donor human milk storage is associated with necrotizing enterocolitis and spontaneous intestinal perforation in preterm infants, particularly those <750 g. These findings suggest a need to reevaluate donor human milk storage guidelines for high-risk neonates, pending multicenter validation.
