P-value indicates differences in physician characteristics between categories of USMG and IMG and is obtained from Generalized Estimating Equations.
P-value indicates there is a differential effect over time (significant interaction of USMG/IMG by time) in which differences in characteristics vary across time therefore no main effects model can be presented (male MD p =0.041; MD age≥65 p<0.001; MD whose primary specialty in FP, GP, IM, geriatrics, p =.045).
P-value from Cochran–Mantel–Haenszel tests to identify the association between whether a MD has ever been board certified during the study time period and race.
FP, family practice; GP, general practice; IM, internal medicine, NA, not applicable.
