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
backgroundUpper gastrointestinal tract anastomotic leaks are associated with increased morbidity and mortality, especially in the 30-day post-operative period. Techniques to reduce tension at the anastomotic site have been postulated to reduce leak rates. Our study investigates if continuous nasojejunal suction (via Freka trelumina tube) compared with standard of care passive free drainage via nasogastric tube results in reduced anastomotic leaks.
methodsA retrospective cohort study was performed on all patients undergoing upper gastrointestinal tract resections with primary high-risk anastomosis (proximal partial, total/extended total gastrectomies and oesophagectomies) over the period between 2012 and 2023 between two major tertiary centres for malignancy. Comparative analysis of outcomes was performed between patients who did or did not receive prophylactic continuous suction, with the primary outcome being the incidence of anastomotic leak. Secondary outcome was the association between patient baseline characteristics and past medical history with anastomotic leaks. Statistical analysis was performed using SPSS v25.0.
resultsOver the 10-year period there were 351 operative cases, with prophylactic suction applied to 62.3% (n = 219) of patients. Overall incidence of anastomotic leaks was 10.3%, with higher proportions from 2-stage oesophagectomies (12.2%), compared with 3-stage oesophagectomies (5.9%) and gastrectomies (6.8%). In the overall cohort, incidence of anastomotic leaks was lower in the suction group (8.7% vs. 12.9%); however, this was not statistically significant (p = 0.210). Further subgroup analyses of 2-stage oesophagectomies showed marginal significance (9.0% vs. 18.9%, p = 0.050). Statistically significant risk factors for anastomotic leaks include any smoking history, elevated BMI, history of ischaemic heart disease, and prolonged operation duration.
conclusionsContinuous gastric conduit suction may reduce the incidence of anastomotic leaks in two-stage oesophagectomies; however, a randomized controlled trial is required to investigate this further.
