Does low-temperature dialysis still represent an advantage?: a narrative review from the last decade.
Review in International urology and nephrology, 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
backgroundLow-temperature hemodialysis (cool dialysis) is a therapeutic strategy aimed at preventing intradialytic hypotension and improving hemodynamic stability in patients with end-stage kidney disease (ESKD). Over the past decade, several studies have investigated its potential impact on cardiovascular outcomes, neurological protection, and clinical tolerability, with sometimes conflicting results.
methodsAn overview of the literature was conducted using PubMed® from January 1, 2015 to July 31, 2025, with the search terms cooler dialysis, cooler dialysate, and cooler dialysate and hemodynamic stability. Randomized and prospective clinical studies assessing the effects of low-temperature hemodialysis on hemodynamic, cardiac, and neurological outcomes were included.
resultsNine studies met the inclusion criteria. Small-scale trials reported a significant reduction in intradialytic hypotension episodes and a protective effect on left ventricular function. The large multicenter MyTEMP trial, while showing no significant reduction in major cardiovascular events, confirmed a trend toward improved blood pressure stability, at the expense of increased thermal discomfort. A Bayesian reanalysis of MyTEMP data suggested a high probability of clinical benefit. Effects on cerebral microcirculation and cognitive function remain uncertain.
conclusionsLow-temperature hemodialysis is associated with improved hemodynamic stability and potential myocardial protection in specific patient subgroups; however, consistent effects on major cardiovascular events or cognitive decline in the general population have not been observed. Large, multicenter studies with extended follow-up are needed to better define clinical indications, long-term outcomes, and the identification of "responder" patients.
