The Effect of Various Types of Motorcycle Helmets on Cervical Spine Injury in Head Injury Patients: A Multicenter Study in Taiwan

Table 3

Multiple logistic regression analyses between case and control groups in helmet types and other covariates and the odds ratio of CSI (Model 2).

OR: odds ratio; CI: confidence interval; CSI: cervical spine injury; and HI: head injury.
The dependent variable in Model 2 was CSI and the independent variables included all variables in Table 1 except helmet use. Only the significant variables ( < .05) were shown in Table 3.
