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
Objective: The risk associated with gastrointestinal foreign bodies in pediatric populations has evolved dynamically over time. Conventional classification may not adequately identify cases that initially present as low-risk but subsequently progress to clinically significant complications. This study aimed to characterize risk trajectories of pediatric gastrointestinal foreign bodies and to evaluate the impact of multidisciplinary team (MDT) involvement on modifying adverse clinical trajectories. Methods: This study employed an explanatory sequential mixed-methods design. A total of 198 pediatric cases with confirmed gastrointestinal foreign bodies were included. Distinct risk trajectories were identified using latent class growth modeling, and multivariable regression analysis was conducted to assess the effect of MDT involvement across trajectory groups. For the qualitative component, purposive sampling identified six representative cases, and the critical incident technique was employed to analyze key decision-making inflection points. Results: Four distinct risk trajectories were identified: stable low-risk (52%;, e.g. coins, smooth objects); slow progression (28%; e.g. early-stage button battery ingestion, single magnet ingestion); sudden high-risk (12%; e.g. multiple magnet ingestion, sharp foreign bodies); and occult perforation (8%; e.g. toothpicks, fish bones, hairballs). MDT involvement was significantly associated with improved clinical outcomes for sudden high-risk trajectory (odds ratio [OR] = 3.87) and the occult perforation trajectory (OR = 5.67) trajectories. Qualitative analysis revealed a recurrent decision-making pathway involving incidental imaging findings, multidisciplinary interpretive conflicts, MDT consultation, subsequent modification of clinical management, and improved outcomes. Conclusion: The management of gastrointestinal foreign bodies in pediatric populations may benefit from moving beyond static classification to dynamic trajectory-based monitoring. MDT involvement is particularly valuable in facilitating timely interventions at critical decision points. A risk monitoring framework incorporating dynamic imaging may support improved clinical management.
