Univariate Predictors of antibody response to COVID-19 Vaccination for S1P and anti- CD20 therapies.

*Statistical significance defined as p < .05.

¹Infusion therapy duration was defined as time on infusion anti- CD20 therapies from first infusion date to first vaccine date.

²Time since last infusion is defined as days between proximate infusion and first vaccine date, where the proximate infusion refers to the infusion date directly prior to the first vaccine date.

³Extended Infusion interval refers to the time between the most proximate infusion prior to the the first vaccine date to the most recent infusion at the time of data collection, and where “extended” was defined as being greater than 194 days, encompassing the standard six month infusion interval (180 days) with a two week grace period (14 days).
