¹The analysis examined the order of the vignette presentation (Order); participants' age, sex, and knowledge of HIV/AIDS, the disease in the vignette, and the presence of a co-characteristic: none, blood transfusion, commercial blood donation (CBD), commercial sex (CS), and injecting drug use (IDU). The sample size for each analysis is also shown: both the total number of participants (P) and the total number of social distance judgments (J).
