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

backgroundA new high-resolution manometry (HRM) parameter, the integrated relaxation pressure (IRP), has been proposed for the assessment of esophageal-gastric junction (EGJ) relaxation. Our aim was to assess the effect of Heller myotomy on IRP in achalasia patients.

methodsWe prospectively collected data on achalasia patients who underwent HRM between 2009-2014. Barium swallow was used to assess esophageal diameter and shape. Manometric diagnoses were performed by using the Chicago Classification v3. All patients with a confirmed diagnosis of achalasia were treated surgically with Heller Myotomy

resultsOne hundred thirty-nine consecutive achalasia patients (M:F = 72:67) represented the study population. All the patients had 100% simultaneous waves but 11 had an IRP < 15 mmHg. At median follow-up of 28 months, the median of IRP was significantly lower after surgery (27.4 [IQR 20.4-35] vs 7.1 [IQR 4.4-9.8]; p < 0.001), and so were the lower esophageal sphincter (LES) resting pressure (27 [IQR 18-33] vs 6 [IQR 3-11]; p < 0.001). At univariate analysis, IRP correlated with the gender, LES resting residual pressure, and dysphagia score.

conclusionsThis is the first study to have examined the role of IRP in achalasia, and how it changes after surgical treatment. An increased preoperative IRP correlated directly with a more severe dysphagia. The IRP was restored to normal by Heller myotomy.
