P values were calculated for comparisions between young and old, comparing all subcategories except the unknown subcategory for all variables; All P values were calculated using the chi-square test unless stated.
a
Skewed,
b
Fisher exact test;
Percentages for each variable were calculated from the respective totals that included the unknown category apart from the YES and NO categories.
