Validation of Subjective and Objective Decisional Trees to prescribe exercise using the pace tool in outpatient older adults.
Article in European geriatric medicine, 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
methodsA tool called PACE, including two decisional trees (SDT for physicians and ODT for exercise professionals), was co-created to integrate PA prescriptions in outpatient geriatric care. The SDT comprised 13 questions from validated questionnaires (FRAIL, FIND, and SARC-F), and the ODT included four geriatric functional tests (30-s chair test, functional reach test, balance, and normal walking speed). SDT and ODT were administered to ninety-seven patients. Cronbach's alpha, confirmatory factor analysis, Pearson's correlation, Kappa, and Tau-B correlation were conducted.
resultsThe SDT and ODT demonstrated good internal consistency (α = 0.74-0.86 and α = 0.75, respectively). Concurrent validity showed significant correlations between the SDT and indices of frailty and sarcopenia (r = 0.62-0.90, p < 0.001) and objective functional tests (r = 0.66-0.72, p < 0.001). The ODT showed significant correlations with functional tests (r = 0.65-0.88, p < 0.001). Despite some correlations between the decisional trees (r = 0.48-0.68, p < 0.001), their concordance was limited (kappa = 0.08-0.41). Sub-analyses revealed higher correlations and concordances when the caregiver living with the patient was involved in SDT responses.
conclusionsThe SDT and ODT demonstrated good validity for assessing the functional performance profile of older adults and can be used to prescribe exercise programs using PACE. This study highlights the importance of involving caregivers in the SDT assessment to refine PACE prescriptions.
