Multivariate model for risk of infections and SIs in (a) OPERA and (b) ORATORIO. (a) Risk of all infections and SIs in OPERA (RMS) over a period of up to 11.2 years. (b) Risk of all infections and SIs in ORATORIO (PPMS), over a period of up to 11.8 years. Significant covariates (p-values < 0.05) are marked in bold.
Covariates were selected from univariate models if their significance level was p ⩽ 0.2. Each model (RMS/PPMS and all infections/SIs) was treated independently, which may result in different covariates being selected. For example, IgG < LLN was not selected for the multivariate analysis of all infections, but it was selected for the multivariate analysis of SIs in patients with RMS in OPERA. Covariates with no results (marked “-”) correspond to covariates not selected from the univariate analysis due to its significance level being p > 0.2. CCOD, November 2022.
