Dyadic associations of physical activity intensity with fertility-related quality of life in infertile couples: an APIM analysis.

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
Objective: Infertility is a condition that intrinsically affects both members of a couple. However, the dyadic associations between physical activity intensity and fertility-related quality of life (FertiQoL) remains insufficiently explored. This study aimed to examine dyadic associations between physical activity intensity and FertiQoL among infertile couples undergoing assisted reproductive technology (ART) treatment. Methods: This cross-sectional study included 364 infertile couples receiving ovulation induction treatment at a reproductive medicine center. Physical activity levels and FertiQoL were assessed using validated questionnaires. Multivariable linear regression was used to examine overall associations between physical activity and FertiQoL domains. The Actor-Partner Interdependence Model (APIM) was applied to estimate actor associations (individual physical activity with own FertiQoL) and partner associations (individual physical activity with spouse's FertiQoL). Results: Women reported significantly lower physical activity levels and FertiQoL scores compared to men (all Conclusion: Physical activity is significantly associated with quality of life among infertile couples in an intensity-dependent manner. More importantly, physical activity demonstrates dyadic interdependence, with wives' physical activity exerting intensity-specific effects on husbands' FertiQoL. These findings highlight the importance of considering couple-level lifestyle behaviors in infertility care and suggest that dyadic lifestyle approaches warrant further evaluation as potential supportive strategies during ART treatment.
