Distinct Subgroups in Gastroparesis Defined by Simultaneous Body Surface Gastric Mapping and Gastric Emptying Breath Testing.

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
backgroundGastroparesis is a heterogeneous disorder with several contributing pathophysiologies. In this study, we used simultaneous body surface gastric mapping (BSGM) and gastric emptying breath testing (GEBT) to subgroup patients with gastroparesis based on dynamic spectral meal response profiles and emptying rate.
methodsPatients with chronic gastroduodenal symptoms and negative gastroscopy underwent simultaneous BSGM and GEBT with 30 min fasting and 4 h postprandial recording. In addition to standard metrics, the BSGM 'meal response ratio' (MRR) compared amplitude in the first 2 h postprandially to the subsequent 2 h (lagged meal response ≤ 1).
resultsOne hundred and forty-three patients underwent simultaneous BSGM and GEBT (79% female, median age 31 years, median BMI 23 kg/m
conclusionCombined BSGM and gastric emptying testing defines subgroups of gastroparesis based on several BSGM abnormalities, including a novel group with delayed postprandial onset of gastric motor activity in association with delayed emptying.
