The effectiveness of generic emails versus a remote knowledge broker to integrate mood management into a smoking cessation programme in team-based primary care: a cluster randomised trial

Table 2 Adjusted odds ratio and 95% confidence intervals for the primary and secondary outcomes

Outcomes^a	No. (%) in group A (knowledge broker)	No. (%) in group B (monthly emails)	Intra-cluster correlation coefficient^b	Adjusted odds ratio^c (95% CI)	P value
Primary: Patient accepted the mood resource at enrollment (n = 2763)	437/1486 (29)	345/1277 (27)	0.141	0.93 (0.60, 1.43)	0.73
Secondary: Patient quit smoking at 6-month follow-up (n = 2136)	345/1160 (30)	279/976 (29)	0.010	1.11 (0.91, 1.35)	0.32

^aThe primary outcome was derived from healthcare providers’ response to the online STOP portal prompt at patient enrollment. The secondary outcome was measured at patients’ 6-month follow-up. The secondary outcome model was limited to patients who responded to the 6-month outcome survey
^bBased on unadjusted models
^cBoth models were adjusted for study stratification variables (organisational readiness and size) and the following patient-level variables measured at enrollment: age; gender; self-reported First Nations, Inuit or Métis status; employment status; education level; household income; smoking status; willingness to quit smoking in the next 30 days; past year alcohol use; past 30-day marijuana use; past 30-day opioid use; sum PHQ-9 score and self-reported lifetime history of depression, anxiety, schizophrenia, bipolar disorder, substance use disorder, alcohol use disorder and problem gambling
