Physical Fitness Index for Older Adults in a Chinese Retirement Community.
Article in Sports (Basel, Switzerland), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundPhysical fitness is important for health and independence in older adults, but existing systems do not always provide a continuous multidomain score.
objectiveTo develop and preliminarily evaluate a Physical Fitness Index (PFI) for older adults in a Chinese retirement community.
methodsA total of 561 participants aged 65-89 years completed assessments of body composition, strength, endurance, balance, mobility, and flexibility. Scores were normalized within sex and 5-year age groups and combined using a fixed radar-axis order.
resultsThe PFI averaged 39.24 ± 13.43 points (range, 4.16-84.47). In a reduced surrogate regression model, R
conclusionThe PFI provides a continuous overall score with a domain profile, but its calibration and measurement properties require external and longitudinal validation.
