Univariate linear association between the absolute changes in insulin levels from baseline (B) to the end of bed rest (BR) with the changes, during the same time period, in midthigh muscle area by computerized tomography (CT; r = −0.55, P = 0.001; A) and whole body fat mass by dual-energy X-ray absorptiometry (DXA; r = 0.53, P = 0.002; B) are shown. Log-transformed insulin levels were plotted and used for analysis.
