a
Migration prevalence defined as the percentage of the ethnic group that spent a period of one month or more living in a different province to their current province in the previous 12 months.
b
The Beta coefficient, R2 and P rows represent the univariate regression analyses of the relationship between migration prevalence and HIV prevalence by ethnic group.
