Determinants of ultrasound-guided reduction failure and pathological lead points in pediatric intussusception.

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
purposeIntussusception is a leading cause of acute intestinal obstruction in children. Ultrasound-guided hydrostatic saline enema (USGSE) is widely accepted as first-line non-surgical management, but predictors of reduction failure and pathological lead points (PLPs) are not well defined.
methodsWe retrospectively reviewed pediatric patients (< 18 years) with ileocolic intussusception treated between 2012 and 2022. Clinical variables included symptom duration, vomiting, bloody stools, and age. Univariable and multivariable logistic regression analyses were used to identify predictors of failed USGSE and PLPs.
resultsEighty-nine patients (93 episodes) were analyzed; 97.85% underwent USGSE as initial treatment. Overall reduction success was 76.92% (70/91) and 90.28% (65/72) in patients without PLPs, with no complications. Symptom duration > 24 h was associated with failed USGSE (OR 4.29, p = 0.0052). After excluding PLP cases, predictors of failure included symptom duration > 24 h (OR 13.97, p = 0.0059), bloody stools (OR 6.83, p = 0.0245), and younger age (p = 0.0094). PLPs were identified in 18 patients (20.2%), most commonly Meckel's diverticulum. Failed USGSE was the sole independent predictor of a PLP (OR 107.26, p < 0.0001).
conclusionUSGSE is safe and highly effective for pediatric ileocolic intussusception. Prolonged symptoms and bloody stools predict reduction failure, while failed USGSE strongly indicates an underlying PLP, supporting prompt intervention and surgical evaluation when reduction is unsuccessful.
