Odds Ratio Estimates of Multinomial Logistic Regression of Active Physician’s MC-FP Status

	Administrative or License Issue (n=232)		Chose to Lapse (n=7,471)		Failed Examination (n=2,321)		MC-FP 7-Year Pathway (n=6,149)		Stage I Complete (n=24,658)
Parameters	OR	95% CI	OR	95% CI	OR	95% CI	OR	95% CI	OR	95% CI
CI=confidence interval; IMG = international medical graduate; MC-FP = Maintenance of Certification for Family Physicians; MUA/P = Medically Underserved Area/Population; OR = odds ratio; PCSA = Primary Care Service Area.
Note: The reference category for MC-FP status is Stage I (n = 28,110); 1,382 observations were deleted because of missing values for the response or explanatory variables.
