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
Objective: This study compared the I-composite graft comprising the right internal thoracic artery and radial artery with the gastroepiploic artery in off-pump coronary artery bypass grafting for severe right coronary artery stenosis. Methods: This study included 78 and 141 patients who underwent right internal thoracic artery-radial artery and gastroepiploic artery grafting, respectively, for off-pump coronary artery bypass grafting between April 2011 and June 2024. Propensity score matching was conducted, and postoperative outpatient follow-up was performed. Results: Propensity score matching resulted in 65 patients in each group. Preoperative characteristics, operative time, and the number of arterial revascularizations and distal anastomoses did not differ significantly between the groups. However, more graft conduits were used in the right internal thoracic artery-radial artery group. Short-term postoperative outcomes were similar, except for a significantly higher early extubation rate in the right internal thoracic artery-radial artery group. During a median follow-up of 5.0 years, overall survival did not differ significantly between the groups. However, the gastroepiploic artery group had a significantly lower long-term freedom from major adverse cardiac and cerebrovascular events, particularly heart failure requiring hospitalization. Multivariate analysis identified a history of peripheral arterial disease as a significant risk factor for overall mortality, whereas the type of right coronary artery graft was not. Conclusions: Using the gastroepiploic artery as a direct conduit for severe right coronary artery stenosis appears to be a promising option when selecting an arterial graft, particularly in improving major adverse cardiac or cerebrovascular events-free survival.
