Costs and recurrence of inguinal hernia repair in premature infants during neonatal admission.
Article in Journal of pediatric surgery, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled it.
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
backgroundTiming of inguinal hernia repair (IHR) in premature infants remains variable, yet the impact of IHR timing on procedure costs and recurrence is unclear. We sought to compare cost and recurrence rates of IHR in premature infants based on timing of repair.
methodsWe performed a retrospective cohort study using MarketScan insurance claims data from 2007 to 2018 to evaluate IHR occurring within 365 days of birth in preterm infants (gestational age [GA]<37 weeks at birth). Patients were stratified based on timing of IHR: those occurring during and after neonatal discharge. Hernia recurrences within one year following IHR were identified. Patient demographic characteristics and costs were compared between groups. Time to recurrence and cumulative recurrence hazards were estimated using Kaplan Meier analysis and Cox proportional hazards regression.
resultsWe identified 3,662 preterm infants with IHR within 365 days of birth; 1,054(28.8%) occurred early. Infants with IHR during NICU stay were more likely to have GA at birth≤32 weeks (74.7% vs. 37.2%; p<0.01) and birthweight<1500 g (83.0% vs. 40.3%; p<0.01) compared to post-NICU IHR. The hernia recurrence rate was higher and total procedure costs lower in early IHR. Early IHR (HR:1.86, 95% CI: 1.56-2.22), incarcerated/strangulated hernia (HR:1.86, 95% CI:1.49-2.32), GA≤32 weeks (HR: 1.40, 95% CI: 1.19-1.65), and congenital anomalies (HR: 1.32, 95% CI: 1.12-1.57) were predictors of hernia recurrence.
conclusionUsing insurance claims data, IHR performed during initial neonatal admission was associated with lower cost, but higher recurrence rate, when compared to delayed repairs in preterm infants. TYPE OF STUDY: Retrospective study LEVEL OF EVIDENCE: Level III.
