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
backgroundThis study aimed to clarify the correlation between anastomotic leakage and anastomotic position after esophagectomy for esophageal cancer, stratified by gastric conduit blood flow assessed using indocyanine green (ICG) fluorescence imaging.
methodsA total of 136 patients who underwent esophagectomy with retrosternal gastric conduit reconstruction were included. After creating the gastric conduit, three points were identified: point A (anastomotic site), point B (terminal end of the gastroepiploic artery stained with ICG), and point C (terminal end of the gastric conduit wall stained with ICG). Anastomotic position was defined by the relative location of point A between points B and C, and blood flow speed before reconstruction (pre-speed) was quantified using ICG fluorescence imaging. Associations of anastomotic position and pre-speed with anastomotic leakage were evaluated.
resultsAnastomotic leakage occurred in 22 patients (16.2%). Mean distance BA (point B to A) was 2.05 cm in the leakage group and 0.15 cm in the non-leakage group (p = 0.018). Mean distance AC (point A to C) was 4.00 cm in the leakage group and 5.89 cm in the non-leakage group (p = 0.016). Logistic regression revealed that BA > -0.50 cm and pre-speed < 2.19 cm/s were independent risk factors for anastomotic leakage (odds ratio 4.67, p = 0.046, and odds ratio 56.16, p < 0.001, respectively). Among patients with delayed blood flow, the anastomotic leakage rate was significantly lower in the proximal group than in the distal group (p = 0.034).
conclusionsICG fluorescence imaging provides useful information for determining an appropriate anastomotic position. Performing the anastomosis at a more proximal site within the gastric conduit may reduce the risk of anastomotic leakage.
