Baseline patient characteristics are listed in the left-most column, with the quantities for those that participated in the genetic study, those that did not, and the P-value for difference between the two in the subsequent three columns. Categorical variables are shown as the number of subjects with that characteristic, followed by the proportion this represents (percentage) in parentheses. For variables that have subcategories, each subcategory and the number and proportion of subjects in that group is shown. Continuous variables are shown as the mean ± the standard deviation. Categorical variables were compared using chi-square or Fisher's exact test. Continuous variables were compared using Student's t-test.
