Statistical analysis
Continuous variables were expressed as mean ± standard deviation (SD) and categorical variables were expressed as numbers (percentages). For comparisons independent Student’s t-test and χ2-test were used for continuous and categorical variables, respectively. Binomial logistic regression was performed to assess association between disease severity and study parameters. All statistical tests were two-sided and a p value <.05 was considered statistically significant. The analyses were performed using Statistical Package for the Social Sciences® version 22.
