Note: † Reference levels in the regressions; virtual variables for Chi-square test; p-value indicated the actual p-values after matching; p#-value indicated the weight to be considered; N (%) were reported. In the county/district presented rural migrant workers with NCMS in the county/district. Across the county/district presented rural migrant workers with NCMS across the county/district.
