  1. All variables with P < 0.1 in univariable logistic regression analysis were shown in this table and all of them were entered into multivariable logistic regression analysis. Nagelkerke R2 statistic was 0.199 and Hosmer and Lemeshow goodness of fit test was not significant at 5% (P = 0.814) in multivariable analysis.
