Discontinuation of continuous kidney replacement therapy in patients with acute kidney injury: A pilot study.
Article in Journal of critical care, 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
backgroundData on discontinuing continuous kidney replacement therapy (CKRT) in acute kidney injury (AKI) remain limited. We investigated whether a standardized approach improved successful CKRT discontinuation.
methodsThis was a pilot prospective study of patients with AKI requiring CKRT in the intensive care unit between 7/2021-3/2024. In the intervention arm, a standardized form was completed daily to guide discontinuation of CKRT. Successful discontinuation was defined as being free from kidney replacement therapy for seven consecutive days. A 2-h creatinine clearance and cystatin C were done at the time of CKRT discontinuation in both arms.
resultsWe screened 373 patients, 32 were included in the standard care and 35 in the intervention arm after satisfying the inclusion criteria. Patients in the intervention arm were more likely to be older (65 vs. 57 years) and require more norepinephrine (0 vs. 0.11 μg/kg/min) on the first day of CKRT compared to standard care. Among survivors at day 7 after CKRT discontinuation, successful discontinuation occurred in 16/23 (69.6%) in the standard care arm versus 19/26 (73.1%) in the intervention arm. When discontinuation was encouraged, CKRT was stopped in 26/35 (74%); when not encouraged, CKRT continued in 53/59 (90%). Performances of cystatin C alone or in combination with 2-h creatinine clearance in predicting successful discontinuation was fair. The best performance was observed in the intervention cohort, AUROC of 0.8 (95% CI, 0.57-0.99).
conclusionA standardized approach did not improve the rate of successful CKRT discontinuation. Future studies are needed before biomarkers are used in decision-making.
