Comparison of BioT Assessed via LC-MS/MS or via Our Prediction Equation for the Total Cohort and From Subsets With Low Total T (≤10.40 nmol/L) or Low BioT (≤2.43 nmol/L)^*

	N	BioT via Prediction Equation, nmol/L	Difference vs LC-MS/MS, nmol/L	Correlation
Total cohort	194	1.84 ± 0.65	−0.10 ± 0.87, P = .126	r = 0.508, P < .001
Low total T	66	1.40 ± 0.42	−0.21 ± 1.01, P = .089	r = 0.663, P < .001
Low BioT	143	1.69 ± 0.59	0.21 ± 0.52, P < .001	r = 0.673, P < .001

^*Values are reported as means standard deviation in SI units for ease of interpretation, but statistical outcomes were calculated using the natural logarithm of these values. To convert BioT to nanograms per deciliter, multiply value by 28.84.
