The association between nutritional intakes and growth trajectories among infants with congenital diaphragmatic hernia: A retrospective cohort study.
Article in JPEN. Journal of parenteral and enteral nutrition, 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
backgroundCongenital diaphragmatic hernia is a critical neonatal condition frequently associated with growth impairment. Nutritional strategies to support adequate growth remain poorly defined.
objectiveTo evaluate the association between caloric and protein intake, timing of parenteral and enteral nutrition, and changes in anthropometric z-scores during neonatal hospitalization in infants with congenital diaphragmatic hernia.
methodsRetrospective cohort study including infants with congenital diaphragmatic hernia who underwent surgical repair at a single center between 2018 and 2023. Data were collected from birth to discharge or 12th week of hospitalization. Weekly deltas in anthropometric z-scores-weight-for-age, length-for-age, and head circumference-for-age-were calculated. Daily caloric and protein intakes were estimated and averaged weekly; timing of parenteral and enteral nutrition and disease-related factors were obtained and associations with anthropometric z-score deltas were analyzed.
resultsA total of 117 infants were included. Overall, 65% experienced z-score declines ≥0.8 across all anthropometric z-scores. Receiver operating characteristic (ROC) curve analysis identified a caloric intake of 113 kcal/kg/day as predictive of positive weight-for-age z-score deltas (area under curve 0.67) with improved specificity at 118 kcal/kg/day. In multivariable linear mixed-effects model, higher caloric intake (p < 0.001) and longer duration of mechanical ventilation (p = 0.01) were independently associated with positive weekly weight-for-age z-score deltas. Additionally, higher caloric intake was independently associated with positive weekly head circumference-for-age z-score deltas (p = 0.02).
conclusionsGrowth impairment during hospitalization was highly prevalent among infants with congenital diaphragmatic hernia. A caloric intake of at least 113 kcal/kg/day, with an optimal threshold near 118 kcal/kg/day, may help prevent further deterioration in weight status.
