  • a Statistical significance, P≤.05.

  • b Exact methods (SAS proc logistic) were used to obtain the 95% confidence interval (95% CI) for odds ratio, as the Wald statistic provided an interval (0.994, 1.18) for general cervical lordosis that was inconsistent with the significance indicated by the likelihood ratio test.
