Utility of a noninvasive urine-based test for diagnosing acute pancreatitis in children.

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
objectivesPediatric acute pancreatitis (AP) is a growing clinical concern with a wide spectrum of severity, from mild episodes to life-threatening conditions. Traditional diagnostic methods primarily rely on serum amylase and lipase measurements, which are invasive and can be challenging in children. This study is the first to evaluate the diagnostic accuracy of the urine trypsinogen-2 dipstick test (UTDT) as a noninvasive test for diagnosing pediatric AP.
methodsThis prospective study included 28 pediatric patients (31 episodes) presenting with acute abdominal pain at a tertiary medical center from November 2022 to October 2024. AP was diagnosed based on the International Study Group of Pediatric Pancreatitis: In Search for a Cure (INSPPIRE) criteria. Urine samples were collected either within the first 24 hours (h) or later during hospitalization. UTDT sensitivity and specificity were calculated and compared to serum amylase and lipase levels.
resultsOf the 31 episodes, 19 (61%) were confirmed as AP, and 12 (39%) were attributed to other causes. The UTDT had an overall sensitivity of 68% and specificity of 100%. Sensitivity increased to 87% when urine samples were collected within 24 h of admission. In non-AP cases, UTDT consistently produced negative results, with the high specificity supporting its reliability in distinguishing AP from other conditions.
conclusionsThe UTDT demonstrates promise as a rapid, noninvasive diagnostic tool for pediatric AP, particularly when used early in the disease course. Its high specificity and ease of use suggest that it may serve as an alternative to invasive blood tests once validated through larger-scale studies. Further research is needed to confirm these findings and establish the role of UTDT in clinical practice.
