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

backgroundPhysical inactivity is one of the most important modifiable risk factors for Alzheimer's disease in North America. Despite this, most older adults are physically inactive. It is currently unknown how to successfully motivate physical activity behavior in older adults at risk for Alzheimer's disease, and this knowledge is crucial for early and effective disease prevention. Prior research has shown that intergenerational social engagement and prosocial behaviours can enhance the health and well-being of older adults.

objectivesThis manuscript describes the design of a randomized controlled trial that will test the efficacy of a behavioral intervention to enhance physical activity in older adults at risk for Alzheimer's disease. DESIGN/

settingThis is a single-blinded, two-arm stratified randomized controlled trial that incorporates a hybrid efficacy and implementation design. Participants are randomized to an intervention or control condition in a 1:1 ratio and are stratified by a multimodal Alzheimer's disease risk score. All study visits are conducted remotely through videoconferencing.

participantsThe study aims to recruit 60 older adults with a first-degree family history of Alzheimer's disease from the PREVENT-AD cohort and 30 younger adults who are paired with older adults in the intervention condition.

interventionOlder participants in the intervention group will be paired with younger study partners and receive positive, daily messages over four weeks using a novel technology platform. The daily messages combine intergenerational social engagement (growing a virtual garden with a younger study partner) and prosocial goals (donations to charity after reaching step count goals). MEASUREMENTS: The primary outcome is change in step count compared to baseline measured using a wrist-worn triaxial accelerometer. Secondary outcomes include time spent physically active, mood, generativity, loneliness, and cognition. Target mechanisms (social support and generativity) of physical activity engagement will be examined. Ease of use, acceptability, and feasibility of the technology as well as barriers and facilitators of participation will be assessed.

conclusionsThis research will advance our understanding of mechanisms and individual differences underlying successful physical activity engagement in older adults who are at risk for Alzheimer's disease. This knowledge will contribute to strategies for promoting health behaviours that can prevent the risk of Alzheimer's disease.
