Echocardiographic predictors of cardiac improvement following coronary artery bypass grafting surgery.

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: To examine markers of improvement in left ventricular (LV) systolic function after coronary artery bypass grafting (CABG), assessed by changes (Δ) in LV ejection fraction (LVEF) and global longitudinal strain (GLS), and to evaluate the association between ΔLVEF/ΔGLS and all-cause mortality. Methods: Patients who underwent isolated CABG from 2006 to 2011 at Gentofte Hospital with a preoperative echocardiography within 30 days before and postoperative echocardiography 30 to 365 days after surgery were included. Multivariable linear regression identified clinical and echocardiographic predictors of ΔLVEF and ΔGLS. Cox proportional hazards regression models related these changes to all-cause mortality. Results: Among 226 patients (median age, 67 years, 14% women), LVEF improved from 48.5% ± 12.8% (pre-CABG) to 53.9% ± 9.8% (post-CABG) and GLS from 12.8% ± 4.4% to 13.6% ± 4.8% (absolute values, both Conclusions: Postoperative improvements in LVEF and GLS were common, occurred most often in patients with lower pre-CABG LV function, and were independently associated with reduced mortality.
