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
backgroundIn chronic kidney disease (CKD), declining physical function predicts adverse outcomes at dialysis initiation, highlighting the importance of promoting regular exercise habits. However, exercise is frequently discouraged immediately before dialysis initiation because of concerns regarding volume overload and hemodynamic instability. Evidence regarding the effectiveness and safety of habitual exercise during this period remains limited. This study examined associations between exercise habits, physical function, and emergency dialysis initiation among patients with end-stage renal disease (ESRD).
methodsThis cross-sectional study included patients with ESRD who initiated hemodialysis at the Hamamatsu University Hospital between August 2022 and April 2025. Exercise habits were assessed using the stages-of-change model, with action or maintenance stages indicating habitual exercise. The outcomes were Short Physical Performance Battery (SPPB) scores at dialysis initiation and emergency dialysis initiation. Associations with SPPB were analyzed using ordinal logistic regression, and associations with emergency initiation were analyzed using modified Poisson regression with robust variance.
resultsAmong 124 patients, 27 (21.8%) had exercise habits. Exercise habits were associated with higher SPPB categories (odds ratio [OR], 5.88; 95% confidence interval [CI] 1.66-20.81; p = 0.008). Emergency dialysis initiation occurred in 27.4% of patients (14.8% vs 30.9%) and was not significantly associated with exercise habits (risk ratios, 0.37; 95% CI 0.12-1.09; p = 0.071).
conclusionsAmong patients with ESRD, immediately before dialysis initiation, exercise habits were associated with better physical function but were not significantly associated with emergency dialysis initiation.
