Association between physical activity and mortality in postmenopausal women: evidence from NHANES 2007-2018.
Article in BMC women's health, 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
backgroundWhether physical activity (PA) levels relate to mortality in postmenopausal women remains not well understood.
methodsWe analyzed 5,880 postmenopausal women from NHANES 2007-2018 (median follow-up:77 months). PA-including total PA (TPA), leisure-time PA (LTPA), and occupational PA (OPA)-was assessed using the Global Physical Activity Questionnaire and expressed as metabolic equivalent of task (MET)-minutes/week. TPA was classified as no, insufficiently active (< 600), or sufficiently active (≥ 600), while LTPA and OPA were classified as no, low (< 600), or high (≥ 600). Weighted proportional hazards Cox models and restricted cubic spline (RCS) analyses examined associations with all-cause, cardiovascular disease (CVD), and non-CVD mortality.
resultsDuring follow-up, 718 deaths occurred (215 CVD, 503 non-CVD). Compared with no PA, insufficiently and sufficiently active TPA were associated with reduced risks of all-cause, CVD, and non-CVD mortality; both low and high LTPA with reduced risks of all-cause and non-CVD mortality; and low OPA with reduced risks of all-cause and non-CVD mortality. RCS analyses showed linear inverse associations for TPA and non-linear inverse associations for LTPA with all-cause and non-CVD mortality, while OPA showed no significant associations. Tests for trend were significant for TPA in relation to all-cause and non-CVD mortality, and for LTPA across all three outcomes. Sensitivity analyses excluding early deaths yielded similar results.
conclusionsHigher TPA and LTPA were associated with reduced risks of all-cause and non-CVD mortality among postmenopausal women. Promoting adequate PA, particularly moving from inactivity to modest levels, may be an effective strategy to support healthy aging in this population.
