Comparisons of the SPA time between levels depending on the grade

  • Average (SD). *Independent samples t test. 95% CI, confidence interval of the difference between averages. Grade I, mild injury; grade II, less severe injury. There were no statistically significant differences in the sports participation absence (SPA) time between the two levels in any of the three grades (p>0.05).
