Renal replacement therapy in type 2 severe cardiorenal syndrome: a randomized controlled trial.
Trial report in ESC heart failure, 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
introductionType 2 cardiorenal syndrome (CRS), characterized by chronic heart failure (HF) leading to chronic kidney disease (CKD), is associated with high morbidity and mortality. In patients with refractory congestive HF, extrarenal fluid removal techniques can be proposed. We aimed to evaluate whether adding ultrafiltration through peritoneal dialysis (PD), haemodialysis (HD), or isolated ultrafiltration (IUF) improves clinical outcomes compared with optimized medical therapy alone.
methodsUltrafiltration Versus Medical Therapies in the Management of the Cardio Renal Syndrome (UF-CARE) was a multicentre, randomized, controlled, open-label trial conducted in 15 French centres. Adults with severe HF, persistent or recurrent congestion despite high-dose diuretics and guideline-directed medical therapy, and mild to severe CKD were randomized to optimized medical therapy alone (Control group) or optimized medical therapy plus ultrafiltration (Ultrafiltration group), through PD, HD, or IUF, according to clinical judgement, patient characteristics and preferences, and availability in each centre. The primary outcome was a composite of all-cause mortality or unplanned hospitalization for acute HF within 12 months.
resultsAmong 108 screened patients, 46 were randomized (24 Control group, 22 Ultrafiltration group). After a median follow-up of 262 days, the primary outcome occurred in 63% of patients in the Ultrafiltration group and 87% in the Control group (P = .144). Quality-of-life scores seemed to improve over time in both groups, with a slightly more sustained improvement in the ultrafiltration group. One death related to the technique was reported.
conclusionIn patients with type 2 CRS and refractory congestive HF, adding ultrafiltration through PD, HD, or IUF did not significantly reduce mortality or HF-related hospitalizations at 12 months compared with optimized medical therapy and close multidisciplinary follow-up, although the trial was underpowered.
