Concussion incidence rates with 95% prediction intervals by sport
Incidence rates and 95%
prediction intervals plotted by
sport. Prediction intervals below
0 were truncated at 0. Sports
were grouped into risk categories
based on k-means of rates.
Group 3 sports, which include rugby, American football, and ice hockey, represent the highest-risk group, followed by groups
2 and 1. Football and wrestling
were male-only sports while
field hockey, gymnastics, and
cheerleading were female-only
sports.
