*OR=exp (beta). A value <1 indicates a decreased risk and a value >1 indicates an increased risk.
†The selection of risk factors in the multivariable logistic regression model was based on Akaike’s information criterion (AIC), corresponding to a p value of 0.157 for a predictor with one regression coefficient.29
