| 5. Reference to theoretical framework | Remove the alternative Regulation | Done |
| 6. Specification of response levels | Introduce one more option between no and yes | We introduced the intermediate option yes, but unclearly |
| DIMENSION 3. OBSERVATIONAL DESIGN | ||
| 9. Justification of the observational design | Introduce one more option between no and yes: partial/incomplete | Done |
| DIMENSION 4. PARTICIPANTS | ||

| 15. Professionalism | Include the options amateur and retired from professional sport | Done |
| 16. Global exclusion of participants | Include it in dimension 11, Data quality control | Done |
| 17. Differential exclusion of participants | Include it in dimension 11, Data quality control | Removed due to Osterlind index results |
| 18. Participants' allocation | It is not applicable in most observational studies. Include it in dimension 11, Data quality control | Removed due to Osterlind index results |
| 19. Activity type | Include physical exercise | Done |
| DIMENSION 5. CONTEXT (SETTING | ||
| 21. Social impact of the activity | Change the options to low/medium/high | Done |
| 28. Observational unit adjustment | Add the option according to the player | Done |
| DIMENSION 6. OBSERVATIONAL INSTRUMENT | ||
