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

purposeReliable predictors of recurrence after non-operative management (NOM) for pediatric uncomplicated acute appendicitis (UCAA) are lacking. Patients and families often face uncertainty and anxiety about recurrence. We evaluated elective interval appendectomy (E-IA) after NOM, focusing on same-day discharge (SDD).

methodsWe retrospectively reviewed patients aged ≤ 18 years who underwent laparoscopic E-IA after successful NOM for UCAA between 2017 and 2025. UCAA was defined as ultrasound grade I/IIa appendicitis without perforation, abscess, or diffuse peritonitis. Characteristics, perioperative outcomes, histopathology, and patient/family and staff satisfaction were analyzed.

resultsA total of 120 patients underwent E-IA (SDD, n = 40; inpatient management, n = 80). Median age was 13.0 years; fecalith was present in 25 patients (20.8%). Median interval from scheduling to surgery was 48.5 days and operative time was 38.0 min. Complications occurred in 3 patients (2.5%), with no unplanned visits or readmissions. SDD was successful in 39/40 patients (97.5%). Recurrence before E-IA occurred in 5 patients (4.2%); all improved with repeat NOM and underwent E-IA. Patient/family and staff satisfaction were 83.3% and 89.3%, respectively. All specimens showed either acute inflammatory findings or chronic/resolving reparative changes, with none classified as histologically normal.

conclusionsE-IA after NOM for UCAA was associated with low morbidity and SDD feasibility, suggesting a potentially new treatment concept for UCAA.
