The relationship between vitamin D levels, comprehensive geriatric assessment and anthropometric measurements.
Article in PloS one, 2025. 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
introductionIt is well-established that vitamin D deficiency increases with age. This study aims to investigate the relationship between vitamin D levels, comprehensive geriatric assessment and anthropometric measurements in elderly individuals.
methodsIn this retrospective cross-sectional analytical study, data from patients aged 65-100 registered with İzmir City Hospital Home Care Services were analyzed. The patients' vitamin D levels were compared with their sociodemographic and clinical data, anthropometric measurements (BMI, ABSI, body fat percentage), and geriatric assessment results (activities of daily living, nutrition, mental status, depression, frailty, and sarcopenia). Data were analyzed using SPSS 26.0 Statistics program.
resultsThis retrospective cross-sectional study included 439 elderly individuals aged 65-100 years receiving home healthcare services. In univariate analysis, no significant associations were found between vitamin D and other variables, except for hypertension (p = 0.049). ABSI values were higher in individuals vitamin D level with severe deficient and deficient compared to other groups, while BMI levels were found to be higher in the vitamin D deficient group (p < 0.001, p < 0.001, respectively). Additionally, the severe deficiency group had a higher frequency of pressure ulcers and lower Barthel Index scores (p = 0.033, p = 0.026, respectively). Correlation analysis revealed a significant negative relationship between vitamin D levels and ABSI (r = -0.184, p < 0.05) and the presence of pressure ulcers (r = -0.113, p < 0.05). Regression analysis confirmed these negative associations with ABSI (β = -0.179, p < 0.05) and pressure ulcers (β = -0.113, p < 0.05). Hypertension and BMI lost their significance in correlation and regression analyses.
conclusionLower vitamin D levels were associated with higher ABSI values and a greater frequency of pressure ulcers. ABSI may be useful in predicting vitamin D deficiency, and monitoring vitamin D levels in patients with pressure ulcers is recommended.
