Summary of logistic and GEE models for smokers and quitters

Variables	OR	95% CI	P-value
Logistic Models for Quitters and Quit Attempts
Quit smoking post-legislation
Scotland vs. UK	0.91	0.47–1.7	0.77
	0.51^d
Any Cessation attempts post-legislation
Scotland vs. UK	0.86	0.56–1.3	0.49
	0.25^d

GEE Model for Use of NRT
Pre-law: Scotland vs. UK	1.9	1.2–2.9	0.0033
Post-law: Scotland vs. UK	0.83	0.53–1.3	0.44
	0.0033^a; 0.0070^b; 0.0077^c; 0.23^d

a: P-value for overall 1 d.f. test for country (UK vs. Scotland)

b: P-value for overall 1 d.f. test for wave (pre- vs. post law)

c: P-value for 1 d.f. test for country × wave interaction

d: P-value for overall 2 d.f. test for SES (low vs. moderate vs. high)
