Sex differences in the associations between illness representations and behavioral intentions to seek early Alzheimer's detection in Chinese older adults.
Article in BMC geriatrics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectivesAlzheimer’s disease (AD) is the most common form of dementia in older adults with no cure. Early detection and intervention are critical for improving patient outcomes. However, behavioral intentions to seek early detection of AD (BI-SEDAD) remain low. Illness representations, referring to individuals’ beliefs about illness, may influence BI-SEDAD. This study aimed to investigate the associations between illness representations and BI-SEDAD among Chinese older adults, and potential sex differences in these associations.
methodsA survey was conducted among 509 Chinese older adults. Participants completed the assessment of BI-SEDAD and illness representations of AD. Moderation analyses were conducted using SPSS PROCESS.
resultsConsequences (β = 0.26), timeline (β = 0.23), illness identity (β = 0.22), illness coherence (β = 0.21), illness concern (β = 0.22), and emotional representations (β = 0.24) were positively associated with BI-SEDAD, whereas treatment control was negatively associated (β = − 0.10). Moreover, sex significantly moderated the associations between BI-SEDAD and consequences (β = − 0.20), treatment control (β = 0.21), illness identity (β = − 0.17), illness coherence (β = − 0.25), and illness concern (β = − 0.26). Specifically, the associations between BI-SEDAD and consequences, illness identity, illness coherence, and illness concern were stronger in males than in females. The association between BI-SEDAD and treatment control was significant only in males.
conclusionsIllness representations are important predictors of BI-SEDAD, with notable sex differences. Tailored interventions that address key beliefs and consider sex differences may promote early detection in older populations.
