  1. a Comparisons of 1999 and 2015, by age group and sex; b Rate ratios (RR) are calculated by applying log-linear regression models to data from all years from 1999 to 2015. Thus, they are not equal to simple RRs calculated using the percentages for the years 1999 and 2015 in this table but are more robust to sudden between-year leaps due to chance
