 Multivariate testing of association of training, drinking, and prevention attitudes with perceived relevance and self reported frequency of alcohol counselling among US medical school seniors (2002-3). Odds ratios are adjusted* and presented with 95% confidence intervals and P values†

	Relevance to intended specialty (n=1215)	Frequency of counselling (n=1237)
Modifiable characteristics
Training in alcohol counselling:
None/some	1.0	1.0
Extensive	2.3 (1.6 to 3.3)	2.2 (1.5 to 3.3)
P value	0.0002	0.0006
Alcohol drinking in past month:
Excessive	1.0	1.0
Non-excessive	1.0 (0.7 to 1.3)	1.2 (0.8 to 1.9)
None	1.4 (0.9 to 2.3)	1.4 (0.9 to 2.1)
P value	0.1	0.3
Physicians have a responsibility to promote prevention with their patients:
Strongly agree	1.4 (0.8 to 2.4)	1.9 (0.8 to 4.4)
Agree	1.1 (0.7 to 1.6)	1.3 (0.6 to 2.7)
Neutral/disagree/strongly disagree	1.0	1.0
P value	0.09	0.08
Control variables
Sex:
Female	1.5 (1.2 to 1.9)	1.1 (0.8 to 1.4)
Male		1.0
P value	0.002	0.6
Current intended specialty:
Primary care	2.2 (1.8 to 2.8)	1.0 (0.7 to 1.3)
Non-primary care	1.0	1.0
P value	<0.0001	0.9

*Odds of reporting “highly relevant” or “usually/always” compared with reference group, adjusted for all other variables listed.
