Incident Heart Failure in Atherosclerotic Renal Artery Stenosis: A Post Hoc Analysis of the CORAL Trial.
Article in Kidney medicine, 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
Rationale & Objective: Although renal artery stenosis (RAS) and heart failure (HF) have been linked, the incidence and predictors of HF among patients with RAS are not well described. Study Design: Post hoc analysis of the Cardiovascular Outcomes in Renal Atherosclerotic Lesions (CORAL) multicenter, open-label, randomized controlled trial (RCT). Settings and Participants: Patients with atherosclerotic RAS and elevated blood pressure, chronic kidney disease, or both, and without a history of HF at enrollment. Intervention: Medical therapy alone versus medical therapy plus renal artery stenting. Outcomes: Incident HF events. Results: This analysis included 808 participants enrolled in the CORAL trial without evidence of baseline HF. During a median follow-up of 4.8 years, 54 participants (6.7%) developed incident HF. HF incidence rates did not differ by randomized intervention (HR, 0.84; 95% confidence interval [CI], 0.49-1.43 for stent arm with medical arm as reference). Baseline diabetes (subdistribution hazard ratio (sHR), 2.07; 95% CI, 1.20-3.58), albuminuria (sHR, 1.12 per doubling of urinary albumin-creatinine ratio, 95% CI, 1.02-1.24), lower eGFR (sHR, 0.78 per 10 mL/min/1.73 m Limitations: This is a post hoc analysis of a RCT. The number of HF events is small. Conclusions: In patients with RAS, rates of incident HF did not differ between participants randomized to optimal medical therapy alone versus optimal medical therapy plus renal artery stenting. The presence of diabetes, PVD, and worse kidney health at baseline were associated with future HF events.
