Table 4. Demographic and Injury Characteristics.

There were no significant differences between groups for either demographic characteristics or initial injury presentation. None of the participant’s characteristics was a significant predictor of subsequent MSK. There were no LOC participants in the No-LEMSK group therefore a binary logistic regression could not be calculated.
