†Multivariate odds ratio (stepwise logistic regression)
using univariate significant variables as input variables. Belief
that SARS is transmittable through droplets or fomites, belief that
there is no effective drugs to treat SARS, and belief that there
would be a resurgence of SARS in China in the coming 6 months were
not univariately significant for any of the 4 dependent variables
(data not tabulated).
