Dyadic patterns of abstinence from smoking in dual-smoking couples enrolled in a pilot randomized clinical trial.

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
objectiveDespite the positive role of social relationships in behavior change, dyadic interventions for smoking have not been consistently successful. This owes, in part, to the fact that dual-smoking cohabiting couples share similar routines, environments, and relational dynamics that can undermine quitting efforts. We adopted an exploratory and descriptive approach to identify distinct profiles of smoking abstinence within dyads, how relationship dynamics relate to these patterns, and whether these patterns predict smoking status at follow-up.
methodWe utilized preexisting data from a pilot RCT examining the effects of partner-involved financial incentives on dyadic abstinence. Both members of 95 dual-smoking couples (52% female, 73% White,
resultsLatent growth mixture models suggested four patterns of dyadic abstinence: Concordant abstainers, Discordant abstainers, Discordant nonabstainers, and Concordant nonabstainers. Treatment arm and motivational and relational dynamics predicted the probability of following specific dyadic patterns of behavior change, and dyadic patterns of change predicted individual and couple quitting status at follow-up.
conclusionsOur findings underscore the importance of considering that treatment will facilitate coordinated dyadic behavior change for some couples but not all and emphasize the need to better understand when and how mechanisms support long-term abstinence. More work is needed to investigate whether these patterns generalize across samples with more diverse sociodemographic and health characteristics.
