Association of Age at Menopause With Lean Body Mass and Sarcopenia Risk in Postmenopausal Korean Women.
Article in The journal of obstetrics and gynaecology research, 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
aimTo evaluate whether menopause at or before 45 years of age is associated with lower lean body mass and a higher risk of sarcopenia in postmenopausal Korean women.
methodsThis cross-sectional study used data from the Korea National Health and Nutrition Examination Survey, 2008-2011. Postmenopausal women aged 40 years or older who underwent whole-body dual-energy X-ray absorptiometry were included. Lean body mass was defined as fat-free soft tissue mass excluding bone mineral content. Multivariable linear regression was used to examine total lean body mass, and logistic regression was used to estimate sarcopenia defined by the appendicular skeletal muscle mass-to-body mass index ratio.
resultsA total of 4244 postmenopausal women were included. Women with menopause at or before 45 years had significantly lower trunk, leg, and total lean body mass than those with menopause after 45 years. After adjustment for age, body mass index, cardiometabolic factors, menopausal hormone therapy, and walking activity, menopause at or before 45 years remained independently associated with lower total lean body mass (regression coefficient, -430.76; p = 0.0084). In the overall population, the association between early menopause and sarcopenia was not significant after adjustment. However, among women with body mass index of at least 23 kg/m
conclusionsEarlier menopause was independently associated with lower lean body mass, and its association with sarcopenia was evident in women with higher body mass index.
