Table IV.

Crude rates per 100 person-months of follow-up and counts of having specific first PPG status transitions by initial PPG

		First transition
Initial PPG status	Total person time (months)	Low		Moderate		High non-tryer		High tryer		Pregnant
		Rate	N	Rate	N	Rate	N	Rate	N	Rate	N
Low	70 624	NA	4825	3.20	2263	0.20	144	0.16	116	0.22	156
Moderate	27 869	6.78	1890	NA	1451	0.71	197	0.70	194	0.63	175
High non-tryera	4897	2.90	142	12.72	623	NA	157	1.35	66	1.72	84
High tryera	1929	Redb	Redb	13.53	261	0.00	0	NA	44	6.48	125

NA: transition rate not applicable because there was no PPG status change.

^aAll high non-tryers and high tryers were automatically moved to moderate if they did not become pregnant within 4 months.

^bRedacted because the N per group was below National Children's Study disclosure avoidance threshold.
