Note: All questions are compulsory. Answer in your own words.
1. Differentiate between the following:
(a) Relative risk and odds ratio
(b) Chi-square tests for association and proportions
2. To study the association between diabetic patients and their family history of diabetes, the following data were obtained on 70 subjects.
| Diabetes in Family | Diabetes in Subject | Total | |
| Yes | No | ||
| Yes | 14 | 3 | 17 |
| No | 3 | 50 | 53 |
| Total | 17 | 53 | 70 |
Which test is appropriate in this situation? Check whether the diabetes runs with generations in families or not at a 5% level of significance using a suitable test
3. Describe censoring and differentiate between different types of censoring with the help of examples
4. A study was conducted on 185 patients aged more than 45 years, which were followed until the time of death or up to 10 years, whichever comes first. The patients have different covariates: age, gender (male/female), systolic blood pressure, smoking (yes/no), total serum cholesterol, and diabetes (yes/no). This study aims to determine which covariate influences the survival time. An analysis is conducted to investigate differences in all-cause mortality between men and women participating in the study. Suppose we obtain the following results after applying the Cox regression hazard model analyses:
| Risk Factor | Parameter Estimate | SE |
| Age | 0.150 | 0.010 |
| Gender | 0.450 | 0.150 |
| Systolic Blood Pressure | 0.015 | 0.008 |
| Smoking | 0.650 | 0.170 |
| Total Serum Cholesterol | 0.002 | 0.004 |
| Diabetes | -0.35 | 0.250 |
(i) Obtain hazard ratio and interpret the results.
(ii) Find the 99% confidence interval for the hazard ratio.
(iii) Test whether the covariates are significant or not at 1% level of significance.
