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

objectiveThis study aimed to quantify domain-specific dose-response relationships between mind-body exercise and cognitive function in older adults with mild cognitive impairment (MCI), and to derive actionable dosing recommendation.

methodsEight major electronic databases were systematically searched up to September 15, 2025. Randomized controlled trials (RCTs) of mind-body exercise intervention in individuals aged ≥60 years with MCI that reported at least one cognitive domain outcome were included. Hedges'g effect sizes were calculated using random-effects models, and dose-response relationships were examined using restricted cubic spline regression.

resultsTwenty-seven RCTs (2034 participants) were included. Moderate-certainty evidence supported improvements in global cognition (Hedges' g: 0.67, 95% CI: [0.49, 0.78]) and processing speed (0.45 [0.3, 0.6]). Global cognition exhibited a U-shaped weekly dose-response, with 240 min/week as the relative nadir that still yielded a significant pooled effect (0.37; [0.19, 0.55]); longer intervention durations significantly amplified this overall response (β = 0.012, p < 0.05), and achieving significant benefit at this dose required ≥11 weeks intervention. Memory followed a similar pattern, but with very low certainty. Processing speed showed a U-shaped cumulative dose-response (nadir: 3400 minutes), and this effect was attenuated by weekly dose (β = -0.0011, p < 0.05), yet caution is warranted because the weekly doses in the included studies were heavily clustered.

conclusionsMind-body exercise produces domain-specific dose-response patterns in older adults with MCI. For global cognition, the observed U-shaped pattern suggests that if 240 min/week dose is adopted clinically, extending intervention to at least 11 weeks is advisable. However, prospective validation of these findings is needed before clinical application.
