  1. * Continuous variables are presented as median with interquartile range and categorical variables as proportions. Does not include the 12 patients with different racial backgrounds
  2. **Calculated using Student's t-test for continuous data that appeared normally distributed, Wilcoxin rank sum for variables that did not appear normally distributed, and the chi-squared test for categorical data.
  3. ALI = acute lung injury; APACHE = Acute Physiology and Chronic Health Evaluation; ICU = intensive care unit; LOS = length of stay; SOFA = Sequential Organ Failure Assessment.
