(Univariable logistic regression models; 7 marks) Consider the two univariable logistic regression models of the outcome dead on the variables male and malaria. a) Present in a table the estimated odds ratios, 95% confidence intervals for the population odds ratio and p-values for the two separate simple logistic regressions. (4 marks) b) Interpret the Odds Ratios for the univariable logistic regression of death and malaria (an interpretation of the p-value and confidence intervals is not required). Since the study population for this case-control study is hospital ‘in-patients’ what further information may you want regarding the patients without malaria infection on admission? (3 marks)
