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

Introduction: Pain constitutes the chief complaint of some functional gastrointestinal disorders (FGIDs). The endocannabinoid (EC) and peroxisome proliferator-activated receptors (PPARs) agonist systems have not been explored as possible contributors. Objective: To determine if EC and PPAR agonist abnormalities occur in adolescents with FGID. Methods: Institutional Review Board approved study compared 33 children (12-18 years) with a FGID to 18 healthy controls (HC). Clinical measures: functional disability inventory and pediatric pain questionnaire (PPQ). Endocannabinoid and PPAR agonist concentrations were determined in serum from blood. Data were analyzed using Mann-Whitney and Fisher exact tests (2-sided Results: When compared to HC, FGID subjects used different terms to describe their pain, which also occurred in more body areas. Functional gastrointestinal disorder subjects exhibited higher palmitoylethanolamide (PEA) and Conclusion: Children with FGID exhibit significant pain in nongastrointestinal regions. The higher concentrations of PEA found in the FGID subjects, also occurring in other chronic pain conditions, could reflect a compensatory response due to feedback loops from a downregulated or nonresponsive PPAR system, while the absence of the expected relationship between pain intensity and PEA levels in the FGID group suggests that the PPAR system may not be functioning normally.
