Linked Lives: Dyadic Trajectories of Cognitive Function Among Middle-Aged and Older Couples.

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
objectivesOur study is among the first to analyze the developmental trajectories of cognitive function at the couple level.
methodsUsing longitudinal dyadic data obtained from 2,130 heterosexual couples who participated in the China Health and Retirement Longitudinal Study between 2011 and 2020, we employed the dyadic latent growth curve model to analyze the developmental trajectories of wives' and husbands' cognitive function from 2011 to 2018. We examined the significant predictors of membership of the latent profiles, as well as the extent to which membership of the latent profiles predicted husbands' and wives' depressive symptoms at follow-up (i.e., in 2018 and 2020).
resultsThe two identified dyadic profiles reflected distinct developmental trajectories at the couple level: high stable couples with outperforming husbands (Profile 1, 81.6% of couples), and moderate stable wives-moderate rapid decline husbands (Profile 2, 18.4% of couples). Husbands' older age and higher number of functional limitations, and couples' residence in rural areas at baseline predicted a higher likelihood of membership in Profile 2. Husbands reporting more chronic conditions at baseline predicted a lower likelihood of the couple being classified in Profile 2. Couples in Profile 2 exhibited higher levels of depression symptoms than their counterparts in Profile 1 in 2018 and 2020. DISCUSSION: Our results highlight the utility of a couple approach in analyzing the developmental trajectories of cognitive functioning in later life and advance our understanding of how couple-level changes exert influence on both spouses' mental health.
