^ For the numbers of new recruits at each survey wave please refer to the ITC-SEA technical report (http://www.itcproject.org/countries/thailand). # For all unique individuals who were presented in at least one wave of the surveys (from Wave 1 to Wave 5), and this applies to the other variables in the table. For some variables the numbers of cases were fewer than the total unique cases, due to some “don’t know” and “missing” cases. ~chi square test results. ** Significant at p < 0.01; *** at p < 0.001.
