Hello everyone,
I would like to ask a question about computing the OR in logistic regression analysis.
I am running a logistic regression model to predict mortality (the outcome), using categorical and continuous variables. In my continuous variables, I have "time delay from diagnosis" variable which is expressed in minutes. When I run the logistic regression, I get OR for every increase in 1 unit of time, but I would like to get the OR for 30 min delay in time, because 1 minute delay is not meaningful in the context of my analysis.
I think I will need to generate a new variable, but I don't know what’s the correct command for that.
Same question for age (years, continuous variable) if I want to compute the OR per 10 years increase and not 1 year.
Thank you for your help
