Early Urine Output in the Emergency Room as a Prognostic Indicator for Critically Ill Patients Undergoing Continuous Renal Replacement.
Article in Life (Basel, Switzerland), 2025. 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
objectivesThe impact of initial emergency room (ER) factors on survival and renal function in critically ill patients undergoing continuous renal replacement therapy (CRRT) remains unclear. This study aimed to evaluate whether these initial factors influence survival and renal recovery in such patients.
methodsThis single-center, retrospective study included 190 critically ill patients admitted to the intensive care unit (ICU) via the ER for CRRT between 1 March 2018, and 31 May 2021. Clinical parameters, including urine output, estimated glomerular filtration rate (eGFR), and serum neutrophil gelatinase-associated lipocalin (NGAL), were assessed. The primary outcomes were 30-day and 90-day mortality, while secondary outcomes included 30-day and 90-day RRT-free durations.
resultsPatients with low urine output (LUO, defined as the average of <0.5 mL/kg/h over 6 h) were significantly associated with higher 30-day and 90-day mortality rates. Multivariable Cox regression analysis revealed that the LUO group had an increased risk of 30-day and 90-day mortality (hazard ratios: 1.935 and 2.141, respectively) compared to the high urine output (HUO, defined as the average of ≥0.5 mL/kg/h over 6 h) group. No significant association was observed between mortality and initial eGFR or plasma NGAL levels. However, the HUO group and patients with initial eGFR ≥ 30 mL/min/1.73 m
conclusionsInitial 6-h urine output in the ER is a significant predictor of 30-day and 90-day mortality in critically ill patients undergoing CRRT.
