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
Backgrounds: We previously reported poor vascularity of narrow gastric tube evaluated by thermography was associated with anastomotic leakage (AL) after esophagectomy. Meanwhile, the association between the fornix low perfusion on devascularized whole stomach (DWS) and the incidence of AL remains unclear. Therefore, this study aimed to clarify the impact of the fornix low perfusion on DWS. Methods: A total of 238 patients who underwent Mckeown esophagectomy with gastric tube reconstruction between 2008 and 2021 were analyzed. Patients were divided into non-AL and AL groups and their clinical outcomes including vascular factors of DWS and gastric tube were compared. Additionally, the logistic regression analysis was conducted to detect the risk factors of AL. Results: AL occurred in 31 patients (13.0%). Regarding vascular factors, avascular area temperature retain rate (Av-TRr) on DWS, right gastroepiploic artery length rate and anastomotic viability index (AVI) on gastric tube were significantly smaller in the AL group than in the non-AL group. In logistic regression model for AL, multivariate analysis showed that diabetes (Odds ratio [OR], 3.90; 95% confidence interval [CI], 1.32-11.60), hand-sewn anastomosis (OR, 4.42;95% CI, 1.05-18.60), Av-TRr on DWS<0.91 (OR, 4.67; 95% CI, 2.00-10.90), and AVI<0.64 (OR, 2.68; 95% CI, 1.12-6.39) were significant risk factors. Conclusions: Fornix low perfusion on DWS was a risk factor of AL as well as low AVI on gastric conduit. Additionally, fornix low perfusion on DWS was correlated with low AVI on gastric conduit.
