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
Background and Aims: The Lyon Consensus 2.0 recommends prolonged wireless pH monitoring for unproven gastroesophageal reflux disease. Endoscopic placement may be limited by cost and resource availability, especially in publicly funded health systems. Transoral placement represents a valid alternative. This study aimed to assess the technical success, safety, and reliability of unsedated transoral wireless pH capsule wireless capsule placement in a Veterans Affairs hospital cohort. Methods: We conducted a retrospective cohort study of patients aged ≥18 years who underwent ambulatory reflux testing from January 2023 to December 2024. Patients were divided into those receiving transoral wireless capsule (TO-WC) placement and those undergoing esophagogastroduodenoscopy (EGD) with wireless capsule (EGD-WC) placement. The primary outcome was technical success. Secondary outcomes included study failures, adverse events, pH study duration, and time-to-capsule placement. Results: Of 120 patients, 41 underwent TO-WC placement and 79 EGD-WC placement. No differences were identified in baseline sociodemographic and clinical variables between both groups. There was a nonsignificant trend toward a lower technical success rate in the transoral group (35/41 [85.4%, TO-WC] vs 75/79 [94.9%, EGD-WC], Conclusions: Unsedated TO-WC placement may be a less successful method for ambulatory pH monitoring in a Veterans Affairs hospital population, especially for prolonged wireless pH testing.
