Interaction P value for the interaction term from a linear model with the sexual variable of interest (1=Rarely or none at all; 2=Some of the time; 3=A lot of the time) as a function of ET intervention arm, linear age group (<60=1; 60–69=2; 70–79=3; 80–89=4), and their interaction.

Among participants who reported sexual activity.
