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 objective: Dementia is associated with impairments in both cognitive and motor function, including gait disturbances and reduced mobility. Although dual-task walking may improve cognitive-motor integration, evidence in dementia remains limited. This study examined whether replacing single-task walking with dual-task walking within an Otago Exercise Program (OEP) provides additional benefits for cognitive function and gait performance in older adults with dementia. Methods: This cluster randomized controlled trial randomized 100 older adults with dementia from 11 dementia care centers to a control group (CG; n = 50) or experimental group (EG; n = 50). Both groups completed a 24-week OEP-based program three times weekly; the EG additionally performed 10 min of dual-task walking per session. Primary outcomes were a composite cognitive score and gait speed. Secondary outcomes included static balance, dynamic balance, and lower-extremity function (knee extensor strength and five-times sit-to-stand test [FTSTS]). Results: Significant group × time interactions were observed for the composite cognitive score and gait speed (both Conclusion: Adding dual-task walking to OEP was associated with greater improvements in cognitive performance and gait speed than OEP alone. Incorporating dual-task walking into such programs may provide additional benefits for older adults with dementia. Clinical trial registration: KCT0010602.
