↵* ORs within each year were adjusted for age, age squared, and parity (9-year lookback).
- †
↵† P value for trend is a result of modeling each outcome on PGD, age, age squared, parity, year, and year-by-PGD interaction. The P value is for the year-by-PGD interaction, to reflect the change in the effect of PGD between 1996 and 2001.
