^‡NS: not statistically significant in multivariable model (applying backward stepwise logistic regression; retaining all variables with a p-value of <0.05 in the model)

*Adjusted for all other variables with an adjusted OR in this table.

^‡The total subject analyzed for the final model were 262 (79/81 cases, and 183/183 controls).
