Elevated Donor-Derived Cell-Free DNA Levels Are Associated With Reduced Myocardial Blood Flow but Not Angiographic Cardiac Allograft Vasculopathy: The EVIDENT Study.
Article in Circulation. Heart failure, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundCardiac allograft vasculopathy (CAV) leads to impaired myocardial blood flow (MBF), increasing the risk of cardiovascular death or retransplant among heart transplantation (HT) recipients. Data on elevation in donor-derived cell-free DNA (dd-cfDNA) and CAV in the absence of rejection are mixed. We sought to test the hypothesis that CAV with reduced MBF (RMBF) is associated with elevated dd-cfDNA.
methodsA retrospective review was conducted on HT recipients at a high-volume center who underwent dd-cfDNA testing between September 2019 and November 2022. Inclusion criteria included undergoing CAV screening with cardiac positron emission tomography scans and coronary angiograms. Patients were grouped by the presence of angiographic CAV diagnosis and MBF reserve evaluated through cardiac positron emission tomography. The latter was subdivided into normal MBF or RMBF, with RMBF defined as an MBF reserve ≤2. Elevated dd-cfDNA was defined as ≥0.12%.
resultsTwo hundred fifty-six HT recipients were included (median age, 55 years; 27.6% female; median, 8 years [interquartile range (IQR), 5-14] post-HT). Ischemic etiology of heart failure was more prevalent in the RMBF group (36%) compared with the normal MBF group (20%;
conclusionsHT recipients with angiographic CAV had similar dd-cfDNA levels and rates as those without. Notably, dd-cfDNA levels and rates were significantly elevated in patients with RMBF assessed by positron emission tomography compared with those with normal MBF.
