	Univariate analyses		Model 1		Model 2
	OR (95% CI)	p-value	OR (95% CI)	p-value	OR (95% CI)	p-value
Male gender	0.77 (0.47–1.27)	0.306
Admission age	1.07 (0.96–1.19)	0.203	1.09 (0.98–1.22)	0.121
Year 1 re-examinations	0.78 (0.42–1.47)	0.442
Year 1 & 2 re-examinations	1.02 (0.77–1.36)	0.866
Total no. of re-examinations	1.06 (1.00–1.13)	0.036			1.03 (0.97–1.11)	0.313
Average medical school grades	0.90 (0.76–1.07)	0.246
Completion time (years)	1.28 (1.05–1.57)	0.016	1.30 (1.06–1.58)	0.011	1.21 (0.96–1.52)	0.102
No. of year 1 dispensations	0.95 (0.38–2.39)	0.913
Total no. of dispensations	1.12 (0.89–1.41)	0.324
n_obs	432		432		432
LR Χ²			8.29		7.00
LR p-value			0.0158		0.0302
Pseudo R²			0.0215		0.0181

OR is the odds ratio; 95% CI is the 95% confidence interval; n_obs = the number of cases and controls used included in the analysis; LR = Likelihood ratio test. The differences in p-values observed in Tables 2 and 3 for the same variables are a result of using different statistics, i.e. t-tests, Χ² test or Fisher’s exact test were used in Table 2 and conditional logistic regression statistics were used in Table 3.
