D3_Total_study_population

study population with entry and exit dates, date of birth, gender, dates and type of vaccinations

D3_TD_all

contains the time-dependent evolution of the binary variable condition. Only changes of status are recorded, with date when the condition changes; the components of the condition last 365 days if they are diagnosis, and 90 days if they are drug proxies; unique spells are created when the algorithm is 1 (if either a dianosis or a drug proxy is active), and the algorithm is reverted to values 0 whenever no component is active

D3_TD_events_complete

contains the time-dependent evolution of all events. Only changes of status are recorded, with date when the condition changes and period end; the components of the condition last 365 days if they are diagnosis, and 90 days if they are drug proxies; unique spells are created when the algorithm is 1 (if either a dianosis or a drug proxy is active), and the algorithm is reverted to values 0 whenever no component is active

D3_TD_covariates_complete

D3_study_population_target_cohorts

contains the list of persons in the study population, with study entry and exit dates, and entry and exit from all the cohorts for incidence/prevalence and for coverage
