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
objectiveSeveral factors are involved in the preservation of graft function after surgical myocardial revascularization. This follow-up study aimed to evaluate the effects of vein graft anastomosis and graft morphology on long-term graft patency a minimum of 10 years after aortocoronary bypass grafting.Setting and Cohorts. This was a sub-analysis of a study that enrolled patients after isolated bypass surgery at the University Hospital Ostrava in order to evaluate the long-term graft patency of the saphenous vein after endoscopic harvest, a minimum of 10 years after aortocoronary bypass grafting.
methodsFifty angiograms, with a total of 90 grafts, after isolated myocardial revascularization were visualized using coronary computed tomography angiography, with 50% luminal stenosis or greater considered significant.
resultsThe overall graft patency rate was 72.3%. The differences in occlusion rates between sequential and individual grafts were not statistically significant (P=0.156). All y-grafts were totally occluded. Graft and target artery diameters had a statistically significant influence on patency (P=1.000 and 0.381, respectively). Longer graft length and higher calcium scores were associated with statistically significant graft occlusion (P=0.033 and 0.005, respectively).
conclusionSequential grafts can be constructed safely, especially when the goal is complete myocardial revascularization.
