Long-term metabolic and cardiovascular health benefits from romantic partner touch in older adults.

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
Interpersonal touch is increasingly recognised as a health-relevant form of social support, associated with improved well-being and stress regulation, with emerging evidence suggesting longer-term physiological associations. Most research on touch has focused on cross-sectional associations of single health markers in young adults, leaving gaps in understanding the association of interpersonal touch with multisystem health over time, especially in groups at risk of low exposure. Chronic stress can have cumulative multiphysiological effects, for example, allostatic load. This study investigates associations between touch frequency with romantic partners and other close adults and components of allostatic load derived from factor analysis, representing three domains: metabolic (C-reactive protein, glycosylated haemoglobin, body mass index, and waist circumference), cardiovascular (systolic blood pressure and diastolic blood pressure), and neuroendocrine (dehydroepiandrosterone and pulse) health measured at two time points five years apart in older adults. Data were drawn from the National Social Life, Health, and Aging Project (n = 787; mean age 73.34y). Cross-lagged path models assessed the relationships between touch frequency and health outcomes, while adjusting for relevant covariates. Frequent touch with romantic partners was associated with more favourable metabolic (β = -0.08,
