Fig. 1From: The association between ambient UVB dose and ANCA-associated vasculitis relapse and onsetAnnual distribution of average daily CW-D-UVB (dashed line) relative to the average daily vitD-UVB (solid line). Values in Dublin (red) and Cork (pink), averaged over 2004–2019, are displayed. The annual peak and nadir of CW-D-UVB were observed in August and February, respectively, lagging behind those of vitD-UVB by 2 months, thus mimicking 25OHD seasonal fluctuationsBack to article page
