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

Objective: No validated scale currently evaluates "interest in health" among older adults. This cross-sectional study assessed the structural validity, internal consistency, and construct validity of the 12-item, 6-item, and 4-item Interest in Health Scale (IHS) in community-dwelling older adults. Methods: A mail survey was conducted in 2024 with 7203 independent older adults in Tsuru City, Japan. Structural validity was examined using exploratory and confirmatory factor analyses. Construct validity was assessed by analyzing the associations between IHS scores and health outcomes. Internal consistency was evaluated using Cronbach's α. Results: Confirmatory factor analysis supported the original three-factor structure of the 12-item IHS (comparative fit index = 0.965), which showed good internal consistency (α = 0.80). Shortened versions strongly correlated with the original version ( Conclusions: The 12-item IHS is a valid and reliable measure for older adults, and its shortened versions may serve as practical screening tools by reducing response burden while maintaining psychometric integrity. The choice depends on balancing brevity for rapid screening with the need for a comprehensive understanding of health values to tailor individual interventions.
