Association between BMI trajectories and metabolic syndrome in postmenopausal women: a cross-sectional study from NHANES 1999-2018.

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
backgroundObesity is an established risk factor for metabolic syndrome (MetS), with both conditions being particularly prevalent among postmenopausal women. However, research examining the relationship between body mass index (BMI) changes across the lifespan and MetS in this specific population remains limited. This study aims to explore the association between BMI trajectories and MetS risk in postmenopausal women.
methodsThis cross-sectional study included postmenopausal women aged ≥ 60 years from the National Health and Nutrition Examination Survey 1999-2018. MetS was defined by 2009 Joint Interim Statement criteria. BMI trajectories over time were identified using latent class growth mixture modeling. Multivariable logistic regression analyses were performed to evaluate the association between distinct BMI trajectories and MetS risk. Subgroup analyses based on reproductive characteristics were conducted to investigate potential effect modification in the relationship between BMI trajectories and MetS risk.
resultsAmong 4061 eligible participants, the overall prevalence of MetS was 71.57% (n = 3070). Three distinct BMI trajectories were identified: stable trajectory (n = 3047, 76.34%), increasing trajectory (n = 540, 12.30%), and increasing-decreasing trajectory (n = 474, 11.36%). Compared with the stable trajectory group, participants in the increasing trajectory group had a higher risk of MetS (OR = 5.09, 95% CI: 3.19-8.13), while those in the increasing-decreasing trajectory group had the highest risk of MetS (OR = 5.89, 95% CI: 3.73-9.31). Subgroup analyses revealed significant effect modification of the association between BMI trajectories and MetS risk by early menopause (P = 0.059), early age at first live birth (P < 0.05), and high parity (P < 0.05).
conclusionsThe increasing and increasing-decreasing BMI trajectory groups are associated with a higher risk of MetS in postmenopausal women. This association is significantly modified by reproductive characteristics. Maintaining a long-term stable BMI may benefit metabolic health.
