Latent profile analysis of physical activity self-efficacy among women with preconception overweight/obesity in Zhengzhou, China.
Article in Preventive medicine reports, 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
Objective: This study aimed to explore the current status and latent profiles of physical activity self-efficacy among women with preconception overweight or obesity. Methods: A convenience sampling method was employed to recruit 400 pregnant women with a preconception body mass index greater than 24 kg/m Results: A total of 388 valid questionnaires were analyzed. Women with preconception overweight/obesity were categorized into three distinct latent profiles: Low Management-Health Education Dependent (45.6%, characterized by reliance on healthcare guidance), Moderate Motivation-Execution Support Limited (44.9%, demonstrating partial self-regulation but constrained by external factors), and High Efficacy-Autonomous Persistence Driven (9.5%, exhibiting strong self-motivation and adherence). Multivariable logistic regression revealed that having an exercise plan during pregnancy, prior knowledge of prenatal exercise, and social support for physical activity were significant influencing factors. Conclusions: Physical activity self-efficacy among women with preconception overweight/obesity was at a moderate level overall, demonstrating distinct classification characteristics.
