Sample size n = 1544, and sample size per subgroup was given as (n). All data is presented as a percentage and 95 CI. Capital letters are used as a label for subgroups within categories for gender, age and sporting frequency. Lower case letters displayed below a specific value indicate that this value is significantly larger than the corresponding capital letters.
