Diagnostic value of the jumping-up test in children with suspected acute appendicitis.
Observational study in Pediatric surgery international, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundDiagnosing acute appendicitis in children is often difficult due to non-specific symptoms and limited cooperation during physical examination. This study aimed to evaluate the diagnostic utility of the Jumping-Up (J-Up) test, and to compare it with traditional physical signs.
methodsWe conducted a prospective observational study from September 2021 to July 2023 in the pediatric emergency department of Asan Medical Center Children's Hospital in Seoul, Korea. Children aged 6-17 years with suspected appendicitis were enrolled. The J-Up test involved instructing patients to jump with both arms raised; the pain response during landing was then assessed. A positive result was defined by visible signs of pain, such as facial grimacing, abdominal guarding, or verbal complaints. Diagnosis was confirmed by contrast-enhanced abdominal CT. The sensitivity of the J-Up test was compared with the sensitivities of rebound tenderness, psoas sign, obturator sign, and Rovsing's sign.
resultsOf the 129 children included, 76 were diagnosed with appendicitis. Mean age was 11.7 ± 3 years and 54.3% (n = 70) were male. The J-Up test was more sensitive (80.3%) than rebound tenderness (69.7%). In complicated cases of appendicitis, the J-Up test had a sensitivity of 92.9%, outperforming the other signs.
conclusionThe Jumping-Up test is a simple and effective tool for diagnosing appendicitis in children, especially in identifying complicated cases. It may serve as a practical adjunct to traditional methods of physical examination in pediatric emergency care.
