The impact of heart valve replacement surgery start time on patients with rheumatic heart disease.
Article in Frontiers in cardiovascular medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objectives: Rheumatic heart disease (RHD) remains prevalent in developing regions, often leading to significant valvular damage. This study aimed to assess whether the start time of heart valve replacement surgery influences short-term clinical outcomes in patients with rheumatic heart disease. Methods: This retrospective analysis included 300 adult patients who underwent elective valve replacement surgery between January 2020 and January 2023. Patients were divided into two groups based on surgery start time: morning (AM group: 7 a.m.-1 p.m.) and afternoon (PM group: after 1 p.m.). Propensity score matching and logistic regression were used to compare mortality, complications, intensive care unit (ICU) stay, and hospitalization. Results: After matching, 283 patients were analyzed (AM: 137, PM: 146). No significant differences were found between groups in postoperative mortality (odds ratios = 0.31, Conclusions: Surgery start time did not significantly affect short-term outcomes in patients with rheumatic heart disease undergoing valve replacement. Differences in hospital stay duration may be attributable to patient-specific factors and surgical complexity.
