Correlations of serum Müllerian inhibiting substance concentration with characteristics of control subjects (n = 204)^*

Characteristic	Spearman correlation	P†
Age, y	−.64	<.001
Height, cm	.01	.87
BMI, kg/m2	.07	.33
Menarche, y	.07	.34
Age at first pregnancy, y‡	−.05	.47
No. of full-term pregnancies	.08	.28

^*Control subjects are from the prospective case–control study of serum Müllerian inhibiting substance and breast cancer risk nested in the Columbia, Missouri Serum Bank. All variables are continuous. BMI = body mass index.

^†P values (two-sided) were calculated by using a t-statistic transformation to test correlation = 0.

^‡Includes 190 parous control subjects.
