Data are represented as numbers and proportion of age group in brackets.
↵a Denotes difference from <45-year age group (P<0.05).
↵b Denotes difference from 45–49-year age group (P<0.05).
↵c Denotes difference from 50–54-year age group (P<0.05).
↵d Denotes difference from 55–59-year age group (P<0.05).
