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
key pointsEarly trial of liberation from continuous renal replacement therapy was associated with improved patient-important clinical outcomes in children with preserved urine output. Hierarchical composite end point analysis demonstrated greater intensive care unit and hospital-free days among patients who underwent a liberation trial. These findings supported early assessment of readiness for liberation using urine output to guide decision making for children receiving continuous renal replacement therapy.
backgroundData to guide assessment of readiness for liberation from continuous renal replacement therapy (CRRT) in children are limited, and hierarchical composite end points have not been applied in this setting. We evaluated whether performing a trial of CRRT liberation among patients with preserved urine output is associated with improved outcomes using a hierarchical end point approach.
methodsWe conducted a retrospective cohort study of patients aged≤25 years from the multicenter Worldwide Exploration of Renal Replacement Outcomes Collaborative in Kidney Disease registry. Patients with urine output >0.5 ml/kg per hour for≥24 hours within the first 5 days after CRRT initiation were included. The primary exposure was a trial of CRRT liberation by day 5. The primary outcome was a hierarchical composite of: ( 1 ) 90-day mortality, ( 2 ) 90-day KRT dependence, ( 3 ) intensive care unit-free days, and ( 4 ) hospital-free days. Inverse probability weighting was used to balance baseline characteristics, and outcomes were compared using a win ratio analysis.
resultsAmong 366 eligible patients, 192 (53%) underwent a liberation trial by day 5. These patients were older, had higher reference serum creatinine levels, and exhibited lower illness severity when compared with those who did not undergo a trial of liberation. In adjusted analyses, a liberation trial was associated with an improved hierarchical outcome (win ratio, 2.14 [95% confidence interval, 1.56 to 2.94], P < 0.001), driven primarily by greater intensive care unit- and hospital-free days.
conclusionAmong CRRT recipients with preserved urine output, a trial of liberation by day 5 was associated with improved outcomes, supporting the early assessment of liberation readiness in patients with a urine output >0.5 ml/kg per hour.
