Dependent Variable	Equation	Specialty	Ratio	Point Estimate of Difference (95% CI)
Verbal dominance	Univariate	IM	1.1	0.16 (0.03, 0.28)^*
		FP	1.3
	Expanded model stratified by patient gender^†
		Male patients
		IM	1.1	0.05 (−0.17, 0.269)
		FP	1.2
		Female patients
		IM	1.2	0.22 (0.05, 0.39)*
		FP	1.4
Patient-centeredness	Univariate	IM	1.1	0.05 (−0.14, 0.23)
		FP	1.1
	Expanded model stratified by patient ethnicity^‡
		White patients
		IM	1.2	0.04 (−0.18, 0.26)
		FP	1.2
		African American patients
		IM	1.1	0.32 (0.01, 0.62)*
		FP	1.4

Verbal dominance is the ratio of all physician’s talk divided by all patient’s talk. Patient-centeredness is the ratio of physician’s psychosocial codes divided by the physician’s biomedical task codes.
