Survival functions from Kaplan Meier curves, showing difference in time up to the DMARD after first intra-articular corticosteroid injection in ANA positive and ANA negative patients. B. Survival function from Kaplan Meier curves, showing difference in time up to the DMARD after first intra-articular corticosteroid injection in patients with and without HLA B27 antigen. C. Survival function from Kaplan Meier curves, showing difference in time up to the DMARD after first intra-articular corticosteroid injection in patients, that were older than 8 years at disease onset and were ANA and HLA B27 negative in comparison to all other patients
