Model A: univariate logistic regression. Model B: multivariate logistic regression.
a
The co-variables adjusted in model B were ascertained based on model A of which variables with a p<0.05 were selected and sex variable as well.
b
The difference between groups was statistically significant (p<0.05). AOR: adjusted odds ratio. The bold values indicate statistically significant (p<0.05). RMB: 100 Chinese Renminbi about 14 US$.
