Effects plot demonstrating the marginal effect of average winter vitD-UVB (kJ/m2) on relapse risk. This is a graphical representation of the multi-level model reported in Table 2 (model 2), controlling for age at diagnosis, gender, AAV phenotype, ANCA serotype and treatment status. The average value for continuous covariates and the baseline value for categorical covariates are depicted. Ticks at the top and bottom of the graph refer to the relapse and remission events, respectively. The predictorEffect function from the effects R package [40, 41] was adapted to create this graphic
