Renal and Cardiovascular Outcomes in Renal Transplant Candidates According to Coronary Status.
Article in Journal of the American Heart Association, 2025. 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
backgroundTo date, there is no consensus regarding coronary artery disease (CAD) screening strategy among renal transplant candidates. This study sought to evaluate the association between the coronary status at waitlisting for renal transplant with both cardiovascular and renal outcomes in renal transplant candidates.
methodsPatients waitlisted for renal transplant were stratified in 4 groups: 1/prior CAD 2/negative screening for CAD 3/positive screening for CAD 4/ no screening. Primary outcome was a composite of death, myocardial infarction, or unplanned revascularization, analyzed with multivariate Cox model including screening group as a time-dependent covariate. Secondary outcome was renal transplantation rates. Negative screening for CAD was considered as reference.
resultsFrom 2005 to 2023, 3248 patients were waitlisted for renal transplantation, among whom 228 (7.0%) had prior CAD, 1987 (61.2%) patients were screened for CAD resulting in 133/1987 (6.7%) of patients with obstructive CAD, and 1033 (31.8%) were not screened. Within a median follow-up of 5.1 years, prior CAD was associated with a higher risk or primary outcome (adjusted hazard ratio [aHR], 1.67 [95% CI, 1.22-2.24]) and with less frequent access to renal transplantation (11.8% at 3 years versus 28.7% for patients with absence of screening). Positive CAD screening was not associated with a higher risk or primary outcome (aHR, 1.20 [95% CI, 0.77-1.77]) but with lower rates of renal transplant (15.0% at 3 years).
conclusionsPatients with known CAD at waitlisting carry the highest cardiovascular burden and have poor access to transplantation. Newly diagnosed CAD based on routine screening at waitlisting was rare and did not have an impact on cardiovascular outcomes but reduced access to renal transplantation.
