  1. Descriptive statistics are presented by parameter and category as applicable. The number of patients with valid data for each parameter are detailed in the third column (Total N); missing category data is detailed as applicable. The descriptive statistics in the fourth column are presented as the mean value ± standard deviation (SD) for continuous variables or as the patient number (N) and percent (%) for categorical variables
