Table 2

Planned secondary outcomes.

---

Patient outcomes:

(i) Biochemically verified 90-day quit rate, measured 6 months after enrollment.
(ii) Number of patients achieving a 50% reduction in the number of cigarettes/bidis smoked in a week, measured at 2 and 6 months after enrollment.
(iii) Correlation between verified quit rates at 6 months and FTND scores at enrollment.
(iv) Correlation between verified quit rates at 6 months and number of quit attempts, by the study group.
(v) Number of patients who report having quit smoking in the last 7 days at 2 and 6 months from enrollment (irrespective of biochemical verification).
(vi) Agreement between self-reported 7-day quit rate and biochemically verified 7-day quit rate, measured at 6 months from enrollment.
(vii) No. of patients who have refrained from using smokeless tobacco in the last 7 days, measured at 6 months from enrollment.
(viii) Per protocol analysis of the 7-day quit outcome, 6 months after enrollment. Patients in the intervention arm who did not receive a hospital counseling session and at least two follow-up phone calls will be excluded.

Medical student outcomes:

(i) Pre-post analysis of medical student knowledge about counseling techniques and pharmacotherapy before, 6 weeks, and 12 months after training.
(ii) Correlation between scores on the knowledge survey with patient quit rates.
(iii) Qualitative analysis of the effectiveness of the training modules assessed by student survey, administered 6 weeks after training.
(iv) Qualitative analysis of student attitudes towards smoking cessation counseling as assessed by a survey, administered 12 months after training.
(v) Qualitative analysis of the trial design and implementation as assessed by a survey administered 12 months after training.
