Prognostic Impact of Untreated Chronic Coronary Artery Obstruction After Surgery for Aortic Regurgitation.
Article in Journal of cardiovascular development and disease, 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
backgroundThe optimal management strategy for 50-70% chronic coronary artery stenosis in patients undergoing aortic valve surgery for aortic regurgitation (AR) remains controversial. This study evaluates the prognostic impact of chronic coronary obstruction severity on surgical outcomes and mid-term survival.
methodsThis retrospective cohort study included 717 patients undergoing aortic valve surgery for AR, grouped by coronary stenosis into <50% (
resultsNo intergroup differences emerged in perioperative mortality (1.32% vs. 1.56%,
conclusionsIn patients with AR, 50-70% chronic coronary obstruction does not increase perioperative complications, MACE, and all-cause mortality.
