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
backgroundIn patients with non-cardiac chest pain (NCCP) and non-obstructive dysphagia (NOD), standard esophageal high resolution manometry (HRM) with water swallows and/or solid meals may miss intermittent dysmotility. To what extent prolonged 24 h-measurements may increase the diagnostic sensitivity is currently unclear.
methods75 patients (47 female, 58 ± 16 years) with NCCP and/or NOD underwent standard HRM (single water swallows plus rice meal) and ambulatory 24-h-HRM with impedance. Results were analyzed according to Chicago Classification v3.0 for water-swallow-HRM; adapted criteria were used for rice-meal and 24-h-HRM. Patients were followed by chart review. KEY
resultsContractility parameters obtained by different HRM procedures always correlated (R > 0.27, p < 0.05). During 24 h-measurements, all parameters showed circadian variability (p < 0.001). In comparison with water-swallow-HRM, rice-meal-HRM markedly increased the proportion of patients diagnosed with achalasia III, esophagogastric outlet obstruction with spastic features, distal esophageal spasm, or hypercontractility (10.7% vs. 21.3%, p = 0.039). The diagnostic gain regarding spastic and/or hypercontractile disorders was further increased by 24-h-HRM (61.3% of patients, p < 0.001). In 11 out of 21 patients with normal results in both water-swallow- and rice-meal-HRM (15% of total cohort), 24-h-HRM detected a major motor disorder. Results of 24-h-HRM altered treatment recommendations in 41 patients (54%). CONCLUSIONS&INFERENCES: 24-h-HRM revealed spastic and/or hypercontractile esophageal motor disorders in about 60% of patients with NCCP/NOD and markedly improved diagnostic yield compared with standard HRM, probably partly due to the observed circadian variability of esophageal motility. 24-h-HRM findings frequently altered treatment recommendations, but the ultimate clinical consequences of the increased diagnostic yield have to be examined further.
