aRisk factors evaluated simultaneously using logistic regression and expressed as Logistic Odds Ratios (OR) with 95% Confidence Intervals (95% CI). All OR adjusted for gender and age.
bOdds ratios with statistically significant results corrected using the formula of Zhang & Kai[30]. Statistically significant differences (p<0.05) are marked in bold.
