Coronary Artery Bypass Grafting Plus Mitral Valve Plasty May Not Provide More Advantage in Patients with Coronary Heart Disease and Moderate Ischemic Mitral Regurgitation: An Inverse Probability of Treatment Weighting Retrospective Cohort Study.
Article in Brazilian journal of cardiovascular surgery, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectiveTo compare the efficacy of isolated off-pump coronary artery bypass grafting (OPCABG) and of coronary artery bypass grafting (CABG) plus mitral valve plasty (MVP) in treating coronary heart disease with moderate ischemic mitral regurgitation to find a better surgical method.
methodsClinical data of 822 patients diagnosed with coronary heart disease and moderate ischemic mitral regurgitation were analyzed retrospectively. Patients were divided into the OPCABG and CABG+MVP groups according to surgical methods. Baseline data of both groups were corrected, and clinical efficacy of the two surgical methods was analyzed and compared using the propensity score inverse probability of treatment weighting (IPTW) method.
resultsThere were no significant differences in the use of mammary artery grafts, number of grafts, and blood product consumption between the two groups (P>0.05) after IPTW. However, the CABG+MVP group had a significantly longer operation time than the OPCABG group (4.13 ± 0.85 hours vs. 5.65 ± 1.02 hours, P<0.001). No statistically significant differences in postoperative major adverse cardiac and cerebrovascular events were observed between the two groups. However, the intra-aortic balloon pump rate was higher in the CABG+MVP group than in the OPCABG group (12.3% vs. 25.0%, P=0.012). Although CABG+MVP can improve ischemic mitral regurgitation significantly (95.4% vs. 81.2%, P<0.001), there were no significant differences in the cumulative survival rate and the incidence of major adverse cardiac and cerebrovascular events between the groups (P>0.05) after IPTW.
conclusionCABG+MVP may not provide more advantage in patients with coronary heart disease and moderate ischemic mitral regurgitation.
