Differences in body composition and baseline serum lipid concentrations between non-responders and responders in terms of salbutamol-induced glucose uptake by brown adipose tissue

(A) Waterfall plot showing the distribution in net glucose uptake by supraclavicular brown adipose tissue (BAT; left and right averaged). Each bar represents the individual value of a participant.

(B–D) Differences in body fat mass percentage (B), waist-hip ratio (C), and baseline serum concentrations of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides (TG), and free fatty acids (FFA) (D) between participants who showed a high salbutamol-induced net glucose uptake by brown adipose tissue (“responders,” blue bars with circles; n = 5) vs. participants who showed low salbutamol-induced net glucose uptake by brown adipose tissue (“non-responders,” white bars with triangles; n = 5). Values illustrated in the figures were measured at baseline during the placebo-visit. A paired Student’s t test, or nonparametric equivalent, was used to compare the two groups. Bars represent means, and error bars represent SD. ∗p ≤ 0.05, ∗∗p ≤ 0.01.
