1 · What the graph read from it

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.

2 · The registry

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

introductionFunctional impairment across degenerative dementias remains understudied in Latin American contexts. We aimed to assess total and item-level functional performance, determine specific instrumental activities, and identify differences in functional profiles between groups.

methodsIn this cross-sectional study, 1445 participants were classified according to the Pfeffer Functional Activities Questionnaire (PFAQ). Statistical comparisons were adjusted for age, sex, and education using linear regression residuals and corrected for multiple comparisons.

resultsFunctional impairment increased progressively from normal cognition to dementia. Alzheimer's disease (AD) and frontotemporal dementia (FTD) groups showed significantly greater total PFAQ scores compared to controls and mild cognitive impairment (MCI). Distinct profiles of impairment emerged: AD was more associated with memory-dependent tasks, while FTD showed disproportionate deficits in executive and social activities. DISCUSSION: Functional abilities are differentially impacted in AD and FTD within the Peruvian population. Our findings highlight the importance of item-level functional evaluation to support early detection and subtype differentiation of dementia in underserved regions. HIGHLIGHTS: We characterized and compared functional abilities among Peruvian older adults with normal cognition and neurodegenerative disease in different stages. PFAQ scores were analyzed across dementia stages in a Peruvian population. Functional abilities were differentially impacted in Peruvian participants with AD compared to FTD. AD was more associated with memory-dependent tasks, while FTD showed disproportional deficits in executive and social activities.
