Injury prevalence and cumulative incidence was calculated as a proportion rate along with 95% confidence interval.Results: The prevalence rate of injuries was 32%. The incidence rate of injuries was 0.67 per 1000km run (95% CI: 0.41- 1.08). The most common anatomical sites for new injuries ...
The persistence rate was defined as 1 minus the probability of experiencing remission, and persistence curves were compared using the log-rank test according to sex and age groups.
