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

backgroundAttentional function is the basis of cognitive function, and its decline affects the daily lives of older adults. Previous studies have not consistently reported the effects of dual-task training (DTT) on attentional function in community-dwelling older adults. This study aims to verify the effectiveness of DTT by combining "motor tasks" and "cognitive tasks involving motor activity" with a focus on inducing dual-task interference (DTI).

methodsThe study design is a randomized controlled trial. The intervention consists of DTT that combines "motor tasks" involving lower limb movements with "cognitive tasks involving motor activity" incorporating complex finger movements. The program will be implemented in a DTI setting, and tasks will be adjusted individually for each participant. The intervention group will be conducted twice per week for four weeks, with each session lasting one hour. The control group will continue with the participants' usual daily activities for four weeks. Attentional function will be assessed as the primary outcome using the Trail Making Test-Japanese and as secondary outcomes using the digit span test and the Stroop and reverse-Stroop test. Balance function will be measured using the single-leg stance test. All evaluations will be conducted at baseline and post-intervention. In the statistical analysis, paired t-tests will be used to compare pre-intervention and post-intervention changes within each group, and analysis of covariance will be used to compare intervention effects between groups. DISCUSSION: Based on the study objectives, the maintenance and improvement of attentional function should be promoted to help community-dwelling older adults maintain healthy lives in familiar environments.
