Note: Comorbidities are classified with the categories listed in the Charlson Comorbidity Index (CCI). COPD stands for chronic obstructive pulmonary disease, PVD for peripheral vascular disease, CHF for congestive heart failure and CEVD for cerebrovascular disease. If the three year average is always higher (lower) than the three year average of the period immediately before, the trend is labeled as increased (decreasing). An increasing trend in incidence is denoted by (+), a decreasing trend by (−).
