Validation of the standard assessment of global everyday activities (SAGEA) scale for dementia diagnosis.
Article in Age and ageing, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundStandardised questionnaires of cognitive symptoms and cognitive-related function can assist in diagnosing dementia. The Standardised Assessment of Global Everyday Activities (SAGEA) is a 15-item questionnaire, developed to measure functional status by capturing cognitive symptoms, basic and instrumental activities of daily living, participation in activites, and mobility.
objectiveThe aim of this study was to validate the SAGEA as a tool for assessing cognitive dysfunction in dementia.
methodsParticipants with dementia, mild cognitive impairment (MCI) or subjective cognitive decline (SCD) were selected from the clinic-based Prospective Registry for Persons with Memory Symptoms (PROMPT), and cognitively asymptomatic, unimpaired controls were selected from the Canadian Platform for Research Online to Investigate Health, Quality of Life, Cognition, Behaviour, Function and Caregiving in Ageing study.
resultsSAGEA scores correlated well with the Lawton-Brody scale for instrumental activities of daily living (r = -0.68, P < 0.0001). SAGEA scores differed significantly across participant groups, highest for individuals with dementia (17.7 ± 8.59) followed by MCI (10.8 ± 9.10), SCD (8.07 ± 7.06) and controls (1.60 ± 2.07). The SAGEA classified dementia with an AUC of 0.97, sensitivity of 94.5% and specificity of 94.6% at a cut-off point of ≥6 points based on Youden's index. A dementia diagnosis algorithm based on the SAGEA distinguished dementia from controls with a sensitivity of 68% and specificity of 100%.
conclusionsThis study supports the utility of the SAGEA as an adjunct to diagnosing dementia and a potentially useful screening tool.
