Prognostic Factors of 30-Day In-Hospital Mortality in Critically Ill Patients Receiving Continuous Renal Replacement Therapy.
Observational study in The journal of nursing research : JNR, 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
backgroundContinuous renal replacement therapy (CRRT) is a form of dialysis that effectively replicates the excretory function of the kidneys in critically ill patients suffering from acute kidney injury. The number of patients receiving CRRT in critical care settings is increasing globally. Although these patients are at greater risk of mortality after commencing CRRT, the comprehensive risk factors for in-hospital mortality in this population remain uncertain. PURPOSE: The prognostic factors for 30-day in-hospital mortality in patients receiving CRRT are investigated in this study.
methodsThis retrospective observational study was performed at a tertiary care university hospital between January 2018 and December 2020. Data from a total of 613 patients requiring CRRT were included. Pre-, intra-, and post-CRRT data were extracted from electronic medical records, and patients were grouped based on 30-day in-hospital mortality into survivor ( n = 300) and nonsurvivor ( n = 313) groups.
resultsThe mortality rate within 30 days of hospitalization was 51.1%. The median survival time calculated using the Kaplan-Meier method was 9 days. The results of multivariate Cox regression analysis revealed hepatic failure as a comorbidity (adjusted hazard ratio [HR] = 2.75, 95% confidence interval [CI] = [1.15, 6.58]), post-continuous renal replacement therapy data including Glasgow Coma Score (adjusted HR = 0.82, 95% CI = [0.72, 0.94]), Sequential Organ Failure Assessment Score (adjusted HR = 1.16, 95% CI = [1.02, 1.32]), and sodium level (adjusted HR = 1.05, 95% CI =[1.01, 1.10]) to be linked to higher in 30-day in-hospital mortality for patients receiving CRRT. CONCLUSIONS/IMPLICATIONS FOR PRACTICE: Based on the findings, early detection and management of changes in illness severity, consciousness levels, and sodium levels during CRRT should be emphasized in ICU care settings. The authors hope the findings contribute to the design and application of transitional care plans for patients undergoing CRRT.
