EVATRAN (The Effect of Eplerenone on the Evolution of Vasculopathy in Renal Transplant Patients): study protocol for a cross-over randomized controlled trial.
Article in Trials, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04450953 (A Randomized Crossover Clinical Trial Regarding the Blockage of the Mineralocorticoid Receptor Using Eplerenone on the Evolution of Arterial Stiffness in Kidney Patients One Year After Transplant), which is not on this 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.

Abstract
backgroundArterial stiffness is a major prognostic factor of cardiovascular (CV) morbi-mortality in kidney transplant (KT) patients. Preclinical studies have demonstrated that the vascular toxicity of calcineurin inhibitors (CNI) is mediated through the activation of the mineralocorticoid receptor (MR) in vascular smooth muscle cells. Additionally, the role of MR in contributing to arterial stiffness is well documented in non-transplanted individuals. This study aims to investigate the impact of MR antagonist treatment on the progression of arterial stiffness in KT patients on cyclosporine.
methodsThis is a randomized, open-label, single-center, cross-over trial involving 36 stable KT patients who have been transplanted for at least 1 year and are maintained on cyclosporine therapy. After a 4-week run-in period, participants will be randomly assigned to one of two groups. Group A will receive eplerenone at a dose of 50 mg daily for 6 months, followed by a 6-month period without treatment. There will be an 8-week washout phase between the treatment and non-treatment periods. Group B will start with 6 months without treatment, followed by the same 8-week washout phase, and then receive eplerenone for 6 months. The primary outcome is to assess the effect of 6 months of eplerenone on arterial stiffness, measured through pulse wave velocity (PWV) using the Sphygmocor® method at the start and end of each treatment period. Secondary outcomes will include changes in (1) central and peripheral blood pressure profiles, (2) intima-media thickness, (3) left ventricular mass, (4) biomarkers of oxidative stress and endothelial dysfunction, and (5) renal graft function markers, such as proteinuria and creatinine levels. Additionally, the incidence of hyperkalemia and episodes of acute renal failure will be monitored. DISCUSSION: CNI are a key component of immunosuppressive therapy in KT patients. By limiting vascular toxicity through MR blockade, CV risk in these patients may be reduced.
