  1. • All values are presented as count (proportion) or median (interquartile range);
  2. • All the available data for the participant demographics were reported with the missing data in each variable excluded, for instance, 11 participants with missing joint-pain data were excluded from the subgroups of former cricketers with and without joint pain;
  3. • ‘Joint pain’: ‘Have you had pain in your hip/groin, knee, ankle, shoulder, hand/finger, spine/back, or other joint(s) on most days of the last month?’;
  4. • ‘Main playing position’: ‘What is/was your predominant position(s) of play?’ Multiple positions could be selected so this was recoded into mutually exclusive categories: ‘batter’ (only ‘Batter’ selected); ‘bowler’ (only ‘Bowler’ selected); ‘all-rounder’ (‘All-rounder’ and/or both ‘Batter’ and ‘Bowler’ were selected); ‘wicketkeeper-batter’ (only ‘Wicketkeeper’ or both ‘Wicketkeeper’ and ‘Batter’ were selected); other combinations of playing positions (e.g. ‘Wicketkeeper’ and ‘Bowler’) (n = 34) were excluded;
  5. • All values are presented as count (proportion) or median (interquartile range);
  6. • ‘Playing standard’: ‘What was the highest standard of cricket that you played for at least one season?’ Responses were dichotomised into ‘elite standard’ (‘International’, ‘County or premier league’, or ‘Academy or county age group’) and ‘recreational standard’ (‘University’, ‘School’, or ‘Village or social’);
  7. • ‘Length of play’: ‘Approximately how many seasons have you played cricket for?’
  8. • ‘Cricket-related injury’: ‘Have you ever had any cricket-related injuries leading to more than 4 weeks of reduced participation in exercise, training or sport?’ If yes, indicate where (hip/groin, knee, ankle, shoulder, hand/finger, spine/back, other joint(s)).
