Long-term analysis of ventricular function in patients with symptomatic coronary disease who underwent on-pump or off-pump coronary artery bypass grafting.

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
backgroundSystemic deleterious effects of cardiopulmonary bypass have been observed in the postprocedural period. Long-term assessment, including ventricular function (VF), is unclear. The objective of this study was to compare the change of left ventricular ejection fractions (LVEFs) during a long-term follow-up of coronary artery disease (CAD) patients who underwent off-pump (OPCAB) or on-pump coronary artery bypass grafting (ONCAB).
methodsThis study is a prespecified analysis of the MASS III trial, which was a single-center and prospective study that enrolled stable CAD patients with preserved VF. The CAD patients in our study were randomized to OPCAB or ONCAB. A transthoracic echocardiogram was performed during follow-up and a LVEF value was obtained. The primary endpoint was the difference between the final LVEF and the baseline LVEF.
resultsOf the 308 randomized patients, ventricular function were observed in 225 over a mean of 5.9 years of follow-up: 113 in the ONCAB group and 112 in the OPCAB group. Baseline characteristics were similar between the two groups, but there was a larger proportion of subjects with 3-vessel disease in the ONCAB group. There was no difference in the LVEF at the beginning (P = 0.08), but there was a slight decrease in the LVEF in the ONCAB and OPCAB groups (P < 0.001 in both groups) at 5.9 years. The decline was not significantly different between the two groups (delta of -6% for ONCAB and -5% for OPCAB; P = 0.78). In a multivariate analysis, myocardial infarction in the follow-up was a predictor of an LVEF < 40%.
conclusionsThere was no difference in the long-term development of ventricular function between the surgical techniques, despite a decline in the LVEF in both groups.
