Optimal cutoff value of integrated relaxation pressure on the esophagogastric junction to detect outflow obstruction using starlet high-resolution manometry system.

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
backgroundAchalasia and esophagogastric junction outflow obstruction (EGJOO) are idiopathic esophageal motility disorders characterized by impaired deglutitive relaxation of the lower esophageal sphincter (LES). High-resolution manometry (HRM) provides integrated relaxation pressure (IRP) which represents adequacy of LES relaxation. The Starlet HRM system is widely used in Japan; however, IRP values in achalasia/EGJOO patients assessed with the Starlet system have not been well studied. We propose the optimal cutoff of IRP for detecting achalasia/EGJOO using the Starlet system.
methodsPatients undergone HRM test using the Starlet system at our institution between July 2018 and September 2020 were included. Of these, we included patients with either achalasia or EGJOO and those who had normal esophageal motility without hiatal hernia. Abnormally impaired LES relaxation (i.e., achalasia and EGJOO) was diagnosed if prolonged esophageal emptying was evident based on timed barium esophagogram (TBE).
resultsA total of 111 patients met study criteria. Of these, 48 patients were diagnosed with achalasia (n = 45 [type I, n = 20; type II, n = 22; type III, n = 3]) or EGJOO (n = 3). In the 48 patients who had a prolonged esophageal clearance based on TBE, IRP values distributed along a wide-range of minimal 14.1 to a maximal of 72.2 mmHg. The optimal cutoff value of IRP was 24.7 mmHg with sensitivity of 89.6% and specificity of 84.1% (AUC 0.94).
conclusionThe optimal cutoff value of IRP to distinguish achalasia/EGJOO was ≥ 25 mmHg using the Starlet HRM system in our cohort. This indicates that the current proposed cutoff of 26 mmHg appears to be relevant.
