Incidence rates (per 100 000 person-years) doubled over the period for AS (57 in 2000\u201302; 114 in 2015\u201317) and for AR (22 in 2000\u201302; 41 in 2015\u201317) and remained the same for MR (38 in both 2000\u201302 and 2015\u201317). Incidence rates increased rapidly with increasing age, most markedly for AS. Men had a higher risk of being affected [relative risk (RR) 1.69 for AS, 1.19 for MR, 1.35 for AR]. Compared to high-level education, patients with medium- and low-level education had a higher risk of being affected (RR 1.18 for AS medium level and 1.47 for AS low level; 1.03 for MR medium level and 1.14 for MR low level; 1.03 for AR medium level and 1.18 for AR low level).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>For AS and AR, the incidence rates doubled, while the incidence rates remained at the same level for MR.
