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

backgroundIntussusception in neonates and young infants is rare, with limited data to guide management.

objectiveThis study aims to characterize the presentation, management, and outcomes of intussusception in infants ≤100 days of age. MATERIALS AND

methodsRadiology reports were searched for the keyword "intussusception" in infants ≤100 days over a 24-year period (January 1, 2000-July 31, 2024). Patient charts were reviewed, and cases with negative imaging studies were excluded. Data were analyzed for patient demographics, presenting symptoms, imaging, and management approach, including operative or non-operative interventions. Intussusceptions were classified as small bowel-small bowel (SB/SB), enteric tube-related SB/SB, or ileocolic.

resultsOf 301 charts reviewed, 124 neonates and young infants ≤100 days of age met inclusion criteria (median age, 55 days; range, 0-100 days). SB/SB intussusception accounted for 94/124 cases (76%), which included 36 (38%) enteric tube-related. Most SB/SB cases were incidental findings, and only two required surgery. Management of enteric tube-related intussusceptions consisted primarily of conservative measures such as tube shortening or removal, with complete resolution and no case requiring surgery. Thirty infants (24%) had ileocolic intussusception. Air enema was attempted in 26, with a success rate of 80% (21/26) and no perforations occurred. Surgical intervention was required in 8 cases, revealing pathologic lead points in 4 cases (duplication cysts - 3; Meckel's diverticulum - 1), corresponding to 13% of ileocolic intussusceptions.

conclusionSB/SB intussusceptions predominate and rarely require intervention. Ileocolic intussusception accounts for 24% of cases, with air enema proving safe and effective in most cases. Most ileocolic intussusceptions are idiopathic (87%), with pathologic lead points identified in 13%, a higher proportion than reported in older children.
