Functional outcomes in pediatric patients on renal replacement therapy in a worldwide registry.
Article in Nephrology, dialysis, transplantation : official publication of the European Dialysis and Transplant Association - European Renal Association, 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
background and hypothesisMortality rates of children supported with continuous renal replacement therapy (CRRT) have improved, yet morbidity remains high. We aimed to evaluate the functional outcomes of children receiving CRRT using Functional Status Scale (FSS). We hypothesized that children receiving CRRT will have worse FSS compared with their baseline and acquire new morbidity at hospital discharge and 6 and 12 months post-discharge, and that lack of renal recovery will contribute to worsening functional status.
methodsThis is a retrospective chart review from The Worldwide Exploration of Renal Replacement Outcomes Collaborate in Kidney Disease (WE-ROCK), an international multi-center registry. Twenty-eight centers across five countries participated in this analysis. Children from birth to 25 years, on CRRT for acute kidney injury (AKI) or fluid overload, were included. Patients with underlying kidney disease, on extracorporeal membrane oxygenation and non-survivors were excluded. FSS was collected at discharge (n = 527), 6 months (n = 387) and 12 months post-discharge (n = 344). The primary outcome was FSS at discharge and 6 months. Secondary outcomes included: new morbidity at discharge and 6 months; FSS at 12 months; and the impact of renal recovery on functional outcomes.
resultsA total of 527 patients had median FSS of 7 (6, 90) at hospital discharge. Thirty-nine percent (n = 204) had worse FSS. Eighteen percent (95/527) acquired a new morbidity at discharge. Predictors of FSS at discharge were baseline FSS {odds ratio (OR) 1.30 [95% confidence interval (CI) 1.11-1.52]}, weight [OR 0.99 (95% CI 0.98-0.9997)], comorbidities [OR 1.88 (95% CI 1.16-3.04)], mechanical ventilation [OR 1.72 (95% CI 1.04-2.85)] and sepsis on intensive care unit admission [OR 1.46 (95% CI 1.01-2.21)]. A total of 387 patients had median FSS score of 6 (6, 8) at 6 months. Ten percent (n = 39/387) acquired new morbidity at 6 months. The significant predictors of FSS at 6 months were FSS at discharge [OR 2.36 (95% CI 1.95-2.84)] and presence of comorbidities [OR 1.77 (95% CI 1.03-3.06)].
conclusionThis is the first large, multi-center study evaluating functional outcomes of children on CRRT. Persistent morbidity following discharge emphasizes the importance of comprehensive identification and multidisciplinary follow-up to optimize patient outcomes.
