Dose outcomes for isotretinoin AT versus ST^∗ visits

	Overall	AT only	ST only	P value
	N = 204	N = 141	N = 63
1st or 2nd HCG, Start	18	13	5	.611‡

	AT overall	AT only	AT with Phone	P value

^∗ST = phone visit (n = 22) plus asynchronous visit converted to phone visit (n = 41).

^†Stop means isotretinoin stopped before course complete (n = 1).

^‡χ² test for homogeneity (2-tailed).
