If no number is presented, the variable is a constant since no statistics can be calculated. Categorical variable: the p value is obtained by a two-tailed chi-square test. a Multivariate analysis after controlling for age. * p < 0.05, ** p < 0.001. If no OR is presented, the variable is a constant since no statistics can be calculated.
