the program.

4.3.2.1 Dataset Simulation

• A virtual clinical trial is simulated to include 100 subjects. Subjects

are randomly assigned to either TRT 1 or TRT 2 at the 1:1 ratio. This

is done by using an SAS function, “ranuni(&seed.)”, which generates

random numbers between 0 and 1. If the random number is less

than 0.5, the subject is assigned to TRT 1; otherwise, the subject is

assigned to TRT 2.

• Subjects’ IOP values are assigned based on a normal distribution

with the preset mean and SD. Subjec ...
