Effect of Prehabilitation on the 6-Minute Walk Test and Length of Hospital Stay in Frail Older People: A Meta-Analysis of Randomized Controlled Trials.
Synthesis in International journal of environmental research and public health, 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
Frailty reduces resilience to surgical stress, increasing vulnerability to adverse outcomes. While recovery efforts traditionally focus on the postoperative phase, the preoperative period offers better opportunities for lifestyle interventions. Prehabilitation aims to increase functional reserve and surgical tolerance, especially in frail older adults. This systematic review and meta-analysis of randomized controlled trials (RCTs) evaluated the effectiveness of multimodal prehabilitation on aerobic capacity-measured by the 6 min walk test (6MWT)-and the length of hospital stay (LOS). A literature search was conducted up to August 2025. Eligible RCTs reported the effects of prehabilitation on functional capacity and LOS. A pairwise meta-analysis was used to calculate pooled mean differences (p-MDs) with 95% confidence intervals (CIs). The risk of bias was assessed via the Cochrane RoB tool, and evidence quality was assessed via the GRADE system. Five studies involving 400 participants were included. The p-MD for the 6MWT showed no significant improvement at any time point: (T1-T2) 9.71 (CI: -38.92; 58.36), (T2-T3) -3.27 (CI: -71.21; 64.65), and (T1-T3) 15.01 (CI: -22.05; 52.07). The LOS was also not significantly reduced (p-MD: -0.464, CI: -0.960; 0.031). Prehabilitation did not significantly improve aerobic capacity or reduce hospital stay. Future research should explore long-term benefits and adherence.
