Development and validation of an Online Comprehensive Geriatric Screening (O-CGS) Tool.
Article in BMC public health, 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
backgroundThe healthcare landscape is undergoing a significant transformation through digitalization. Embracing digital technology presents an opportunity to enhance the health and well-being of older adults. Therefore, this study aimed to develop and evaluate the validity and usability of an online comprehensive geriatric screening (O-CGS) tool for intrinsic capacity declines.
methodsBetween September 2023 and September 2024, 381 community-dwelling Thai adults aged 55 and above were recruited at the health check-up clinic of a university hospital in Bangkok, Thailand, using convenience sampling. To evaluate the validity, all participants had completed an initial online self-administered assessment followed by face-to-face reference standard assessments. Sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, positive predictive value, negative predictive value, and accuracy were reported.
resultsAmong 381 participants, the median age was 64.8 years, with 85% being female. The prevalence of geriatric syndromes ranged from 2.4% (frailty) to 50% (cognitive impairment). The sensitivity of the screening tool varied from 48% (for sarcopenia) to 100% (for depression), while specificity ranged from 54% (for fall risk) to 98% (for sarcopenia). Notably, the newly developed online cognitive screening tool demonstrated acceptable performance in detecting mild cognitive impairment and severe cognitive impairment, with a sensitivity of 61% and specificity of 63%. On average, participants spent 37 min completing the O-CGS. Additionally, participants reported high satisfaction with the tool, with a mean score of 4.4 out of 5.
conclusionsThis study demonstrated the satisfactory performance and feasibility of a self-administered O-CGS tool, aligning with the healthy aging concept.
