Difference of genotype distribution between patients grouped in quartiles according to total T levels and controls. SS = homozygous for short CYP19(TTTA)n alleles (nine or fewer repeats); SL = heterozygous for short CYP19(TTTA)n alleles; LL = homozygous for long CYP19(TTTA)n alleles (more than nine repeats).

Difference in T/E2 ratio between patients being homozygous (SS) for short CYP19(TTTA)n alleles (nine or fewer repeats) and patients being either heterozygous (SL) or homozygous (LL) for long CYP19(TTTA)n alleles (more than nine repeats).
