  1. All differences between means and proportions are significant (P ≤ 0.0001). Adults defined as aged ≥ 20 years; childbirth-related discharges not included. aCaucasian results were calculated with data from four states (Florida, New York, New Jersey, and Massachusetts). bIntensive care unit results included hospitalizations for only five states (Florida, New York, New Jersey, Massachusetts, and Washington).
