Note. Race excludes patients that declined to respond or selected “other”. a Analyzed using Pearson’s Chi-square test for categorical variables or t-test for continuous variables, unless noted differently. b Due to small cell count, analyzed using Fischer’s Exact test. c N = 101 for acute vs. chronic symptom duration analyses. d Values are means (SD).
