Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. To measure the variation in NNN and NNK levels across tobacco products. 2. To prove that after adjustment for duration and intensity of product use, higher carcinogen levels in SLT products will lead to higher biomarker levels in users. 3. To prove that OHNC patients will have higher levels of biomarkers than SLT users without cancer. Timepoint: Spot sampling (once only) | — |
Secondary
| Measure | Time frame |
|---|---|
| Capacity building and sustained collaboration 1. National tobacco product repository at Healis-Sekhsaria Institute for Public Health in Mumbai 2. Biospecimen repository: Samples collected from SLT users will be part of the biospecimen repository which will be hosted by the Tata Memorial Hospital 3.Strengthening laboratory capacity at ACTREC will serve not only to complete the proposed studies, but also as a critical long-term resource for other tobacco exposure studies in India.Timepoint: Not applcable | — |
