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
Although chronic total occlusions (CTO) are a common finding in patients treated with coronary artery bypass grafting (CABG), it is still not clear how their presence impacts the long-term outcomes achieved with surgery. We aimed to investigate the impact of CTO on the long-term results of patients with coronary artery disease who underwent CABG. Patients from 2005 to 2023 operated on at the University Hospital Freiburg-Bad Krozingen were analyzed. The primary outcome was all-cause mortality after 3-, 5-, and 10 years. The secondary outcome was the need for coronary reintervention in the follow-up period. Propensity score matching and multivariable Cox regression were performed, and Kaplan-Meier curves were used to graphically display the outcomes for the two groups. Of the 3424 patients included in the analysis, 1784 (52%) were categorized as CTO and 1640 (48%) were categorized as no-CTO. After propensity scoring, 1232 pairs were successfully matched. The 3-, 5-, and 10-year all-cause mortality was significantly higher in patients with CTO (
