1 · What the graph read from it

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.

2 · The registry

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

backgroundThe purpose of this study was to explore the associations of low muscle mass with serum sex hormones and sex hormone-binding globulin (SHBG) using data from the National Health and Nutrition Examination Survey (NHANES).

methodsWe analysed 4403 adults aged 20-59 years from the 2013-2016 NHANES. Appendicular skeletal muscle index (ASMI) was calculated as appendicular skeletal muscle (kg) divided by height squared (m

resultsThe mean age of the participants was 38.6 years (± 11.35 years), and 46.3% of the participants were female. In men, both total testosterone (TT) (Model 3: OR = 1.003, 95% CI: 1.002-1.004, p < 0.001) and free testosterone (Model 3: OR = 1.007, 95% CI: 1.001-1.013, p = 0.022) levels correlated positively with low muscle mass. The highest TT quartile had 4.529 times the odds compared to the lowest quartile (Model 3: OR = 4.529, 95% CI: 1.927-10.645, p = 0.003). Each unit increase in SHBG was associated with higher odds (Model 3: OR = 1.035, 95% CI: 1.024-1.045, p < 0.001). The highest SHBG quartile (> 45.26 nmol/L) showed 6.442-fold higher odds (Model 3: OR = 6.442, 95% CI: 3.134-13.242, p < 0.001). For women, the highest estradiol quartile (> 116 pg/mL) had 56.4% lower odds of low muscle mass than the lowest quartile (Model 3: OR = 0.436, 95% CI: 0.268-0.709, p = 0.004). Each unit increase in free testosterone (FT) showed an inverse association (Model 3: OR = 0.710, 95% CI: 0.605-0.834, p < 0.001). The highest FT quartile (> 3.70 pg/mL) had 73.7% lower odds (Model 3: OR = 0.263, 95% CI: 0.146-0.473, p < 0.001). Each unit increase in SHBG showed a positive association with low muscle mass (Model 3: OR = 1.009, 95% CI: 1.007-1.012, p < 0.001). The highest SHBG quartile (> 87.21 nmol/L) showed 5.482-fold higher odds (Model 3: OR = 5.482, 95% CI: 2.854-10.527, p < 0.001).

conclusionsIn women, estradiol and free testosterone levels are negatively associated with low muscle mass. In men, elevated total testosterone was unexpectedly associated with an increased risk of LMM. SHBG elevation is a consistent risk factor across sexes.
