4 A randomized controlled study was performed to assess the efficacy of financial incentives on quitting smoking. A total 878 employees (who smoked) of a multinational company based in United States were randomized to either: - receive information about smoking-cessation programs (442 employees) : the control group - receive information about programs plus financial incentives (436 employees): the intervention group The primary outcome for this stu was quitting smoking within 12 months after randomization. (we will refer to this simply as "quitting smoking") The results from a simple logistic regression of the study results are as follows: In(odds of quitting smoking) = -2.95 + 1.20x1 , where x1 = 1 for the intervention group, and 0 fo the control group. The standard error of the intercept is 0.20, and the standard error of the slope for x1 is 0.25 be viens off - What is the odds ratio (and 95% CI) of quitting smoking for the financial incentives groups (intervention) compared to the information (control) only group? X1= 1 in
