Among South Asians (Figure 6), health insurance, age, employment, and citizenship status were identified as important delineating variables.

Among Vietnamese women (Figure 7), 72% of women without a pap exam did not had a mammogram in the previous two years (node 2); however, this was the only discriminating variable selected by RP. Excluding the pap and colorectal cancer screening variables (data not shown), marital status emerged as an additionally impor- tant predictor; among Vietnamese women who have never been married, 67% did not have a mammogram in the previous two years. Additional analyses showed that Vietnamese women who have never been married were significantly more likely than women who have been mar- ried to have had pap and/or colorectal screening, and were more likely (not significant) to be employed more than 30 hours per week and to receive public assistance.
