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
Background and Purpose: Given the irreversible nature of dementia, this study examined the effects of a 20-week exercise-based dementia prevention program in community-dwelling older adults, focusing on prior exercise experience and program adherence. Methods: In this exploratory, non-randomized trial, 55 older adults (65-79 years) were allocated to an intervention (n=26) or control (n=29) group, and blinding was not feasible. The intervention comprised supervised rhythmic aerobic exercise with cognitive-motor components performed three times per week. Cognition was the primary outcome, and secondary outcomes included physical fitness, blood pressure, and blood biomarkers. Subgroup analyses classified participants by prior exercise experience and intervention exposure: G1 and G2 comprised control subgroups with no intervention exposure, whereas G3 and G4 comprised intervention-exposed subgroups stratified by adherence. Results: No significant group-by-time interactions were observed for cognitive outcomes. Participants with prior exercise experience and low adherence (G2) showed significant improvement on the Korean Mini-Mental State Examination (β=1.66, Conclusions: Although overall cognitive gains were modest and not group specific, prior exercise experience and sustained adherence were associated with favorable changes in physical fitness and vascular outcomes, suggesting that tailored multicomponent exercise programs and long-term engagement may help promote cognitive health in older adults.
