Multivariate linear regression of factors associated with SHBG

Variable (unit) β (95% CI) Cumulative R2 Δ R 2 P-value
BMI (kg/m2) –1·23 (–1·35, –1·11) 0·10 – <0·001
Age (year) 0·31 (0·24, 0·37) 0·14 0·04 <0·001
Albumin (mg/dl) –8·3(–10·1, –6·4) 0·16 0·02 <0·001
Calculated free testosterone (pmol/l) –0·07 (–0·09, –0·05) 0·17 0·01 <0·001

For the analysis above, the total R2 value for all variables in the model is reported as ‘cumulative’ R2. The individual R2 value for any specific variable can be found under the column ‘ΔR2’.
