1 · What the graph read from 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.

2 · The registry

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

purposeInguinal hernia (IH) occurs frequently in extremely- and very-low-birth-weight (ELBW/VLBW) infants. This study evaluates the feasibility of performing laparoscopic repair (LR) near neonatal intensive care unit (NICU) discharge, by comparing its perioperative outcomes with those of open repair (OR) in ELBW/VLBW infants.

methodsWe retrospectively reviewed infants with birth weight < 1500 g who were diagnosed with IH during NICU hospitalization and underwent IH repair between 2015 and 2023. LR was performed using the laparoscopic percutaneous extraperitoneal closure (LPEC) technique. We compared the patient characteristics, operative variables, and postoperative outcomes between the groups.

resultsAmong a total of 49 infants, 31 underwent OR and 18 underwent LR. The LR group had a higher body weight at surgery, a lower prevalence of chronic lung disease, and different sex distribution. Operative and anesthesia times were similar for unilateral repair but shorter with LR for bilateral repair. There were no significant differences in postoperative complications. Three infants from the OR group underwent subsequent umbilicoplasty, and one developed a metachronous contralateral hernia.

conclusionLR appears technically feasible with acceptable short-term outcomes and may allow contralateral evaluation and concomitant umbilicoplasty. However, baseline imbalances, the small sample size, and limited follow-up preclude conclusions regarding superiority or equivalence to OR.
