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
backgroundAnastomotic leakage (AL) remains a major complication after cervical esophagogastric anastomosis. Although indocyanine green (ICG) fluorescence imaging has been used to assess gastric conduit perfusion, its role in structured intraoperative decision-making and the temporal stability of outcomes remain unclear.
methodsThis single-center retrospective study included 507 consecutive patients who underwent esophagectomy with cervical esophagogastric anastomosis using the modified Collard technique under a standardized ICG-guided protocol. Intraoperative ICG imaging was used to identify poorly perfused distal conduit segments for exclusion. Temporal trends were evaluated using moving average and cumulative sum (CUSUM) analyses.
resultsAnastomotic leakage occurred in 19 patients (3.75%), including clinically relevant leakage (grade ≥ III) in 13 (2.56%). Reoperation was required in one case, with no leakage-related mortality. ICG assessment prompted additional proximal resection in 49.9% of evaluable patients, reflecting frequent detection of marginal distal perfusion; however, final anastomoses were consistently constructed within adequately perfused zones. Temporal analyses, including CUSUM, demonstrated sustained performance below a stringent 5% target rate throughout the study period.
conclusionsA standardized ICG-guided intraoperative decision-making strategy for cervical esophagogastric anastomosis using the modified Collard technique was associated with a low (3.75%) and temporally stable anastomotic leakage rate. Rather than serving as a binary perfusion test, ICG imaging functioned as a practical rule-out tool to exclude clearly unsafe conduit segments. When embedded within a structured decision-making framework, this approach enabled consistent implementation and durable reconstructive quality in routine clinical practice.
