D3_PERSONS

Contains the cleaned version of PERSONS, where birth date and death date are reconstituted as dates

D3_events_DEATH

Contains the deaths observed in the study population

D3_output_spells_category

Contains the spells exited from CreateSpells, i.e., all the continuous spells of observation period of each person, stratified per op_meaning. op_meaning is by default the same for all observation periods, and is set in 05_subpopulations_restricting_meanings for those data sources where the analysis is conducted on subpopulations having different sets of data banks

conceptsetdataset

These are multiple datasets, one per each conceptset, which is a value in the list c(conceptsets_exact_matching, conceptsets_children_matching), set in 07_algorithms. Each conceptset dataset is named after the conceptset. Each conceptset is associated to a list of codes. The dataset is obtained by retrieving records from the CDM bearing a code that match one of the codes in the codelist. The matching can be exact (for the conceptsets in conceptsets_exact_matching) or per ascendant (for conceptsets in conceptsets_children_matching) . Records are retrieved from the EVENTS table, but also from other tables which may bear a record, such as PROCEDURES or VACCINES

D3_clean_vaccines

This dataset contains all the records of a COVID vaccine, including their imputation and modifications and exclusion criteria. Exclusion criteria must be applied before using the variable in the next steps

D3_vaccines_curated

This dataset contains only the records of a COVID vaccine that enter the study

Flowchart_criteria_for_doses

Flowchart of the exclusion of covid vaccines records

D3_clean_spells

Contains the spells exited from CreateSpells plus their binary variables that are to be used for cleaning purposes version; spells that fall outside the interval between birth and death are cut, and op_start_date that start before the baby is 60 days are recasted to birth (to be checked with DAPs)

D3_selection_criteria_from_PERSONS_to_study_population

Contains the exclusion criteria to go from PERSONS to the study population
