1 · What the graph read from it

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.

2 · The registry

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

<p>Introduction: Patients with end-stage kidney disease develop cognitive impairment due to comorbidities and dialysis dependence. Among community-dwelling older adults, cognitive (CT) and exercise training (ET) are promising interventions to preserve cognition; these interventions may be tailored for adults undergoing in-center hemodialysis.

methodsAdult (≥18 years) English-speaking patients undergoing hemodialysis (within 3 months to 3 years of initiation) were enrolled in a 2 × 2 factorial randomized controlled trial: Interventions Made to Preserve Cognitive Function Trial (IMPCT). Participants (n = 121) were block-randomized (September, 2018-February, 2023) into 4 arms: control (SC) (n = 26), intradialytic web-based CT (n = 31), ET using foot peddler (n = 29), and combined CT+ET (n = 35). Participants underwent assessments at baseline and 3 months for executive function, global cognitive function, clinical outcomes, and patient-centered outcomes. We estimated 3-month executive function change (primary outcome) and secondary outcomes using linear regression.

resultsThere were no differences in 3-month executive function change by arm. Participants exhibited improvement in 3-month global cognitive function in CT+ET arm (Montreal Cognitive Assessment score difference = 2.1, 95% CI: 0.4-3.9), and self-reported 3-month improvement in perceived health change (score difference = 0.8, 95% CI: 0.2-1.4) in ET arm.

conclusionClinicians may encourage CT+ET for hemodialysis patients to improve short-term global cognitive function and perceived health. The long-term benefits of these interventions warrant further study. </p>.
