Model adjusted for race, marital status, study period, medical history, AMI-associated characteristics, and length of stay.
p values for interaction terms between age and study period
NA: Not applicable. Among men, since age differences in AF and cardiogenic shock have changed significantly over time, adjusted ORs for each study period were calculated separately and are presented in the text; there were no overall ORs for these outcomes.
