Effect of the Independent Variables on the Risk of Ankle Sprain ()
The effect each variable had on the rate of ankle sprain is shown in Table 5. The risk of sustaining an ankle sprain was twice as high (risk ratio, 2.14; 95% CI, 1.25-3.65; P = .005) for subjects who had sustained an ankle sprain within the previous 12 months. Taking part in the intervention program significantly reduced the risk of an ankle sprain (risk ratio, 0.56; 95% CI, 0.33-0.95; P = .033). This finding indicates that the intervention program was very effective in reducing the number of ankle sprains.
