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
objectivesFrailty and social vulnerability are two dynamic and multidimensional constructs able to capture susceptibility to adverse health outcomes related to physical decline or arising from weakened social connections, support, and resources. While the burden of physical frailty in dementia has been well established, the impact of disadvantageous social conditions is less known. In this study, we investigated these dimensions in Alzheimer's disease (AD) and frontotemporal dementia (FTD) with the aim of describing possible common and individual trajectories.
methods47 individuals living with AD and 24 with FTD, as well as 66 healthy control (HC) subjects, were included. An ad hoc developed 60-item bidimensional Frailty Index (FI) questionnaire was administered to explore the two dimensions. Global (gFI), physical (pFI) and social (sFI) FI scores were derived and compared among groups with ANCOVA, including age and education as covariates. Pearson's correlation analyses explored the relationship between FI scores and clinical-neuropsychological measures.
resultsNo group effect was observed for pFI. Both patient groups showed significantly higher gFI and sFI levels compared to HC. sFI positively correlated with disease severity and cognitive patterns in both dementias.
conclusionOur findings point to an urgent need for person-centered care strategies that extend beyond biomedical models. Deficits in social connections and support represent a primary and common underpinning of vulnerability in dementia populations. A timely periodic evaluation of non-physical determinants of vulnerability may contribute to a better and earlier detection of maladaptive trajectories with a consequent beneficial effect on the well-being and burden of the patient-caregiver dyad.
