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

backgroundBody surface gastric mapping (BSGM) non-invasively assesses gastric myoelectrical activity along with real-time symptom reporting. In adults, the development of normative intervals has underpinned new explanatory phenotypes, aiding clinical decision-making. This study established normative reference intervals for adolescent BSGM metrics.

methodsHealthy adolescents aged 12-17 years with a BMI ≤ 35 kg/m KEY

resultsA total of 107 participants (52.8% female, median age 14 [IQR 13-16], median BMI 20.1 [IQR 18.75-22.40]) with mixed ethnicities were included. No substantive correlations were observed between BSGM metrics and demographics or anthropometric data. Therefore, a single set of normative reference intervals was established. Median PGF was 3.06 cycles per minute; reference interval 2.72-3.37. Median BMI-adjusted amplitude was 37.80 μV; reference interval 20.0-72.0. Median GA-RI was 0.51; reference interval ≥ 0.22. Median ff-AR was 2.12; reference interval ≥ 1.0. CONCLUSIONS AND INFERENCES: This study presents normative reference intervals for BSGM spectral metrics in adolescent populations, informing the interpretation of tests in research and clinical practice.
