Thank you very much for your answer. What about using this in a multivariable model? Should I transform all continuous variables using log(X)/log(2)? In a univariate model = X compared to model = Log(X)/Log(2), the p-value also changes.

Is it possible to calculate the OR for the risk of doubling the value of X? I know that I can use UNITS = 1 or UNITS = SD, but I don't understand that people are reporting ORs for doubling X, as doubling might be from X = 1 to X = 2 (that's a one unit change) but also e.g. from X = 2 to X = 4 (which is a 2 unit change). This would give different ORs. Therefore, I wonder if it is possible to calculated just one OR for doubling a specific covariate.
