Trajectories and Predictors of Physical Activity in Women with Gestational Diabetes Mellitus in Guangzhou, China: A Prospective Study.
Article in International journal of women's health, 2025. 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
Purpose: This study analyzed physical activity (PA) trajectories, identified subgroups, and explored their associations in women with gestational diabetes mellitus (GDM). Methods: From January to November 2024, a longitudinal study was conducted using convenience sampling to recruit women with GDM from a maternal and child health hospital in Guangzhou (China). General information and baseline PA data were collected at diagnosis (24--26 weeks of gestation), and follow-up PA assessments were carried out at 28, 32, and 36 weeks. The Pregnancy Physical Activity Questionnaire (PPAQ) was used to assess PA levels. The latent class growth model (LCGM) identified distinct PA trajectories. Results: Of the 236 women enrolled, 223 completed follow-up. PA scores increased from T0 to a peak at T1 (median 156.45 MET·h/w, IQR: 113.08-221.10), then declined to a low at T3 (114.63 ± 47.30 MET·h/w). LCGM identified three trajectory subgroups: high-level reduction (4.04%), moderate-level fluctuation (43.50%), and low-level stable (52.47%). Ordinal logistic regression showed that unemployment (odds ratio (OR): 4.754; 95% confidence interval (CI): 1.878-12.037) and exercising alone (OR: 2.268; 95% CI: 1.219-4.225) were significantly associated with subgroup membership ( Conclusion: PA levels in women with GDM initially rose and then declined, with most sustaining stable low activity. Unemployment and solitary exercise were significant predictors of lower PA trajectories.
