Marital dynamics and daily memory among aging same-sex and different-sex 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
objectivesIn older adulthood, a spouse is often the closest relationship and a key source of support for health. Although prior research emphasizes the importance of marital dynamics for cognition, it predominantly focuses on different-sex couples. This leaves a critical gap in understanding how these processes might differ for aging same-sex couples. To address this gap, we examine how marital support and strain are associated with daily memory function among aging couples, exploring whether these associations differ between same-sex and different-sex marital dyads, with particular attention to gender differences.
methodsUsing 10-day dyadic diary data collected from 556 individuals aged 41-71 in same-sex and different-sex married couples, we estimate mixed-effects multilevel models to assess the associations between respondent- and spouse-reported marital dynamics and daily memory.
resultsMarital strain-but not marital support-is significantly associated with daily memory failures among aging couples. This association is particularly pronounced for women in different-sex marriages compared to men and women in same-sex marriages and men in different-sex marriages. No significant partner effects are observed. DISCUSSION: Our findings demonstrate that marital dynamics are linked to cognition and that these associations may vary in important ways for couples of different gender compositions. This study highlights the importance of identifying relationship-specific processes that may support or undermine cognitive health for aging couples across diverse marital contexts.
