Any drug use in the past year 10.0% 57.7% 22.7% 54.8% 64.5%
  1. Probabilities greater than 50% indicates that individuals are likely to have reported a given risk factor, and are bolded to facilitate interpretation
  2. This table assumes a 3-class structure for the nationwide survey and a 2-class structure for the Guangzhou sentinel surveillance dataset
