I had a few questions about the data that are generated in the full report and it would be great to have someone address these questions. I am using ATLAS 2.5.0.
Can someone explain why the age distribution is expressed as a median with interquartile range instead of a mean with standard deviations? How are these numbers calculated and are there any bugs people have noticed?
What is the baseline person-year exposure? Is it the product of the amount of time each patient has been in the cohort multiplied by the total number of patients?
What is the observation length in the observation period tab? Is this the median follow up time of cohort patients (per capita) from the index date onward?
