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
objectivesEvaluate the performance of diagnostic measures (sensitivity and specificity) of the Intrinsic Capacity (IC) construct by domain and by age group. STUDY
design164 elderly individuals were assessed in the 5 domains of IC (cognition, psychological, vitality, locomotion, and sensory) and for Activities of Daily Living (ADL), Instrumental Activities of Daily Living (IADL), frailty, and urinary incontinence. One-way ANOVA, t-test, or Mann-Whitney test were used for quantitative variables, and chi-square test for qualitative variables. The sensitivity and specificity were evaluated using the ROC curve.
resultsDecline in IC was older, worse ADL, IADL, and mental function, low gait speed, higher depression scores, frailty, and urinary incontinence. The full version and the cognitive, psychological, locomotion, and sensory domains demonstrated moderate performance, while the vitality showed poor performance. The age-stratified analysis indicated that among participants aged 60-69 years, the cognitive, vitality, locomotion, and sensory domains showed poor performance, while the psychological domain demonstrated good performance. In the 70-79-year group, all domains showed moderate performance. In individuals aged ≥ 80-years, the cognitive, psychological, vitality, and locomotion domains demonstrated moderate performance, whereas the sensory domain showed good performance.
conclusionsFull IC construct and most domains showed moderate performance, with the exception of vitality (poor performance). When analyzed by domain and age group, performance varied across domains, ranging from poor to moderate, with the sensory domain showing the best results in the oldest group. Furthermore, the intrinsic capacity construct remains a useful screening approach for identifying older adults at risk of frailty.
