Natural history of inguinal hernia in neonates and infants: clinical regression and incarceration.
Article in Pediatric surgery international, 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
purposeIn our institution, infants with inguinal hernias are managed with elective repair at approximately 1 year of age to reduce perioperative complications and allow for possible clinical regression. This study aimed to clarify the natural history of infantile inguinal hernia and identify factors associated with clinical regression and incarceration.
methodsWe conducted a retrospective chart review of patients diagnosed before 1 year of age between 2015 and 2023, supplemented with telephone follow-ups to confirm clinical regression. Factors associated with clinical regression were analyzed, and the time to incarceration was evaluated using a Fine-Gray competing risks model with surgery as a competing event.
resultsIn total, 357 patients were included. Clinical regression was confirmed in 45 patients, including 33 term infants with a median follow-up period of 5.3 (IQR 3.9-8.0) years. In multivariable analysis, older age at diagnosis was independently associated with a lower likelihood of clinical regression (odds ratio: 0.65 [0.51-0.82]). Incarceration occurred in 43 patients and was associated with male sex (multivariable subdistribution hazard ratio: 2.68 [1.19-6.02]).
conclusionDespite the risk of incarceration, a watchful waiting strategy may be acceptable for selected patients when careful follow-up and prompt access to care are available.
