*SARS, severe acute respiratory syndrome; RR, relative risk; CI, confidence interval; UD, undefined; ICU, intensive care unit.
The optimal location and design behavior in all intervals is undefined.
For descriptive purposes we report proportions with their 95% Wald CIs and exact 95% CIs in cases in which Wald intervals were undefined.
