Logistic and Cox proportional hazards regression are used widely in medical and epidemiologic studies for analyzing the relationship between several risk factors and a time-related dichotomous response variable. Suppose we are studying the risk factors associated with mortality of Covid-19 patients admitted to hospitals in the Philippines. The response variable is whether or not the patient with Covid-19 died at the end of their hospitalization. Other variables recorded were: the time to death of the patient, sex, age, vaccinated or not vaccinated, presence of comorbidities, severity of Covid-19, variant of Covid-19, etc. In this study, would you prefer using the logistic regression or the Cox PH regression? Justify your answer. Site some of the advantages and disadvantages of preferring one method over the other.
