Adjusted^a mean hormone concentrations by CYP17 MspA1 I and SRD5A2 V89L polymorphisms in 622 British men

^a Values are adjusted for age (in categories of 20–29, 30–39, 40–49, 50–59, 60–69, 70+), time of day at venipuncture (<10, 10–13.29, 13.30+ h), time since last meal at venipuncture (<1.5, 1.5–<3, 3+ h), and time between blood draw and processing (1, 2, 3, 4+ days).
^b P is test for heterogeneity across the mean hormone concentrations in each genotype (see text).
^c Test of heterogeneity between two means; where two superscripts are the same, V/V genotype is different from V/L genotype at P < 0.05.
^d Test of heterogeneity between two means; where two superscripts are the same, V/V genotype is different from L/L genotype at P < 0.05.
^e Test of heterogeneity between two means; where two superscripts are the same, V/L genotype is different from L/L genotype at P < 0.05.
