Survival of suspected, probable, or confirmed cases of EVD by treatment given. The Kaplan-Meier survival functions for the time period including 30 days after the reported onset of symptoms is presented for suspected, probable, or confirmed EVD cases. Survival functions are stratified by the highest level of treatment received, which was categorized by those who were hospitalized (blue line, n = 162), those who were quarantined with other individuals suspected of having EVD (gray line, n = 70), and those who were isolated (red line, n = 159). The equality of survival functions assessed by log-rank tests was significantly different by the highest level of treatment given (P < 0.001)
