Table 1. Patient Characteristics.
Means (SD) are presented for the continuous variable “age”, and N(%) presented for all other categorical variables. Group differences for continuous variables were tested by one-way analysis of variance with Bonferroni’s adjustment for multiple comparisons, with p-value presented. The χ2 test for independence was used to examine group differences for categorical variables with p-value presented.
