OCS usage
All OCS prescriptions were converted into prednisolone-equivalent doses
(equivalences available in Online Supplement Table E1 ). We
calculated the number of OCS prescriptions and accumulated daily dose
per OCS-user. All individuals in the study population were classified
annually by their respective cumulative OCS consumption within the given
calendar year, categorized in three exposure groups (21);
- a no-use group
- a low-use group, defined by use of <1825 mg in the
given year, corresponding to <5 mg OCS/day (not including 0
use), and
- a high-use group, corresponding to ≥5 mg OCS/day
