Step 3

Create outcomes and covariate variables on the study population

D3_events_OUTCOMESIM_simple

Contains the outcomes observed in the study population, including negative outcomes but excluding covid and complex algorithms

D3_events_OUTCOMECOMPL_complex

Contains the outcomes observed in the study population, including only complex algorithms

D3_events_ALL_OUTCOMES

Contains the outcomes observed in the study population, including negative outcomes but excluding covid

D3_covid_episodes

Contains the episodes of COVID observed in all persons in the study population. Each episode is separated from the next by at least 60 days

D3_covid_episodes_description

Contains the description of the episodes of COVID observed in all persons in the study population. Each episode is separated from the next by at least 60 days

QC_covid_episodes

Occurrence of components of covid, per meaning, to all persons in the study population

D3_covid_severity_components_hospitalisation

Contains the episodes of COVID in D3_covid_episodes that had level of severity 'intensive care unit (ICU)'

QC_covid_severity_components_hospitalisation

Occurrence of components of covid hospitalisation, per meaning, to all persons in the study population

D3_covid_severity_components_ICU

Contains the episodes of COVID in D3_covid_episodes that had level of severity 'hospitalised'

QC_covid_severity_components_ICU

Occurrence of components of covid ICU, per meaning, to all persons in the study population

D3_covid_severity_components_death

Contains the episodes of COVID in D3_covid_episodes that had level of severity 'death'

QC_covid_severity_components_death

Occurrence of components of covid death, per meaning, to all persons in the study population

D3_TD_variable_COVID

Contains the time-dependent evolution of the categorical variable COVID. Occurrences are recorded with their level of severity. The date is the date of the first information about the infection, information about severity may accrue across time

D3_covariates_ALL

Contains the covariates observed in the study populationin two points in time: at baseline, and at first vaccination (if any)

QC_all_components_OUTCOME

Occurrence of components of the outcome OUTCOME during 2019 (and to be dropped, during one year of lookback), per meaning, to all persons in the study population at 1/1/2019 or entering during 2019
