Recruitment
|
||||||||||||||||
Recruitment details |
Subjects initiated on glucocorticoid treatment at the same time as the trial treatment were recruited into the "Prevention algorithm". Subjects already on established glucocorticoids were recruited into the "Treatment algorithm". The recruitment into the "Prevention algorithm" ended up not feasible and not analysed. | |||||||||||||||

Notes [1] - The number of subjects reported to have started the pre-assignment period are not the same as the worldwide number enrolled in the trial. It is expected that these numbers will be the same. Justification: this inconsistency is due to withdraws prior to commencing treatment |
