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
Purpose: This study aimed to comprehensively identify the etiologies and distribution of subtypes of organic and non-organic chronic abdominal pain (CAP) and to examine their associations with clinical features in children. Methods: This single-center, observational, retrospective study included 384 pediatric patients (1.9 -18 years) whose chief complaint was abdominal pain lasting at least 2 months and who visited or were admitted to a tertiary hospital between March 2009 and February 2019. Results: Functional abdominal pain disorders (FAPDs) were the most prevalent etiology of CAP (88.3%), followed by organic causes (8.4%) and functional constipation (2.6%). Regarding the subgroup distribution of FAPDs, functional abdominal pain-not otherwise specified-accounted for the highest proportion (70.2%), followed by irritable bowel syndrome (15.3%), functional dyspepsia (12.7%), and abdominal migraine (1.8%). Among patients with FAPDs, 4.7% had comorbid psychiatric disorders, and 1.2% had intended weight loss. Organic causes included gastritis associated with Conclusion: A comprehensive understanding of the etiologies and characteristics of CAP in children may facilitate the development of a structured clinical approach guided by alarm signs and symptoms for this prevalent and challenging condition.
