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

backgroundPoor hand dexterity may increase the risk of functional disability; however, few studies have examined the relationship between hand dexterity and incident functional disability. The aim of this study was to prospectively investigate the dose-response association of hand dexterity with incident functional disability in community-dwelling older adults.

methodsThis study included 1,069 older adults aged ≥65 years in Kasama City, Japan. Peg-moving and circle-drawing tasks were used to evaluate hand dexterity. Functional disability was identified using the Japanese Long-Term Care Insurance System database. Restricted cubic spline analysis was performed to investigate the dose-response association between hand dexterity and incident functional disability.

resultsDuring a mean follow-up of 8.5 years (maximum 14.0 years), 248 participants (23.2%) developed functional disability. The lowest performance group in each hand dexterity test had a significantly higher risk of functional disability than the highest performance group-peg-moving (hazard ratio [HR]=1.92, 95% confidence interval [CI] 1.29-2.87) and circle drawing (HR=1.66, 95% CI 1.15-2.41). Spline analysis confirmed curvilinear dose-response associations between hand dexterity and incident functional disability. Increased risk was observed when participants performed worse than the cut points (peg-moving, 37.9/38.0 seconds; circle drawing, 21/20 points), and no decreased risk was observed for those who performed better than these cut points.

conclusionEasily evaluated hand dexterity tests may be valuable for predicting functional disability in older adults. Curvilinear dose-response associations suggest that maintaining adequate hand dexterity could be a key strategy to support functional independence.
