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
Delayed gastric conduit emptying (DGCE) is a debilitating functional complication after esophagectomy. Because of a lack of large-scale outcome data, this project evaluated surgical revisional strategies for refractory DGCE within a recently published mechanism-informed classification system. REvisional Surgery for delayed gasTRic conduit emptying (RESTORANT) was a multicentric, retrospective cohort study including adult patients undergoing revisional surgery for DGCE from January 1, 2015, to December 31, 2024, across 26 high-volume centers that performed 11,807 esophagectomies during this period. Patients were eligible irrespective of the date of their index esophagectomy. Interventions were stratified into Class 1 (pylorus-related, C1), Class 2 (conduit-related, C2), and Class 3 (hiatus-related/paraconduit hernia, C3), with class assigned retrospectively according to the revisional procedure performed. The primary endpoint was reported symptom resolution. A total of 196 patients underwent 263 surgical interventions for DGCE. Sustained symptom relief was comparable across all classes: C1 (47.2%), C2 (58.2%), and C3 (63.9%; P = 0.165). For C1, pyloroplasty (47.6%) and Roux-en-Y diversion (46.7%) showed similar efficacy. In C2, conduit replacement (75.0%) and remodeling (61.3%) were significantly more effective than simple mobilization (50.0%; P = 0.035). For C3, paraconduit hernia repair achieved higher resolution than crural division (65.8% vs. 47.1%). The overall complication rate was 32.7%, with significantly higher major morbidity and mortality in C2 (20.0% and 3.6%) compared with C3 (13.4% and 1.7%) and C1 (16.7% and 2.8%, P = 0.047). Multivariable analysis identified no independent predictors of surgical success but was limited by heterogeneity and sample size. RESTORANT provides the first multicentric analysis of surgical DGCE repair. While symptom resolution is achievable across all classes, C2 interventions carry increased risks. These findings may help structure future prospective audits.
