Presented are the final reduced multivariable logistic regression models for Analysis 1: Vietnamese-immigrant/Mekong Delta Vietnamese; Analysis 2: Vietnamese-immigrant/Australian-born. Both main and interaction effects are included, with reference group indicated in the left column where applicable. Interpreting findings at the main effect level must be treated with caution in the presence of a significant interaction effect (indicated by italicized OR and 95% C.I. indices). Note: different reference groups are used for the age variable between analysis 1 and 2.
