Groups Categorized by Magnitude of Total Testosterone Level Variation

	Group 1	Group 2	Group 3	P Value
Population, n (%)	322 (63)	120 (24)	64 (13)	-
Age, median (IQR)	65 (58, 70)	62 (55,68)	64 (58,69)	0.23
Morning TT, median (IQR)	349 (286, 445)	548 (444, 713)	368 (294, 442)	0.01
Afternoon TT, median (IQR)	347 (272, 439)	374 (255, 449)	566 (480, 648)	0.01

Group 1: TT no significant difference between am and pm levels (−100 to + 100 ng/dL).

Group 2: decrease in TT level in pm (−100 ng/dL).

Group 3: increase in TT level in pm (+100 ng/dL).

TT = Total Testosterone; IQR = interquartile range.
