I am working on logistic regression. I have a binary response variable (PASI response:yes,no) and three categorical covariates-

treatment (treatment A, treatment B),

body weight (below 60kg, above or equal to 60kg)

and therapy taken (yes, no).

I need to calculate the following from the logistic regression model using SAS:

1. Adjusted response rate and standard error for treatment A and for treatment B,

2. Adjusted response rate difference and standard error between treatment A and treatment B,

3. 90% confidence interval for the adjusted response rate difference.

We use SAS in our organization for analysis. Can anyone please tell me how to do these using SAS?

Many thanks in advance !
