Table 1.
Patient characteristics by disease groups. Continuous variables are summarized by mean, standard deviation (SD), median, and interquartile range (IQR). Categorical variables are summarized by frequency and proportion. The p-values were from one-way ANOVA tests of the mean difference among the 4 groups for continuous variables, and from Fisher’s exact tests of the proportions among the 4 groups for categorical variables. Missing data were excluded from testing.
