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
Total coronary revascularization via anterior thoracotomy (TCRAT) enables complete anatomical revascularization without sternotomy; however, data on its impact on left ventricular function remain limited. This study compared left ventricular functional outcomes between TCRAT and median sternotomy coronary artery bypass grafting (MS-CABG) in 554 patients undergoing elective isolated CABG at four centers (January 2020-January 2025) with preoperative and ≥3-month follow-up echocardiography. Patients were grouped as TCRAT (n = 241) or MS-CABG (n = 313). Stabilized inverse probability of treatment weighting was applied to reduce selection bias, achieving adequate covariate balance (all standardized mean differences < 0.10). The primary endpoint was follow-up left ventricular ejection fraction, assessed using IPTW-weighted analysis of covariance adjusted for preoperative values. No significant difference was observed between groups (β = 0.13; 95% CI, -0.63 to 0.90;
