Note: The Diabetes Care in American Samoa (DCAS) intervention was a cluster-randomized, culturally tailored, home-visiting CHW intervention. Results are shown as number (percentage) or mean ± standard deviation. P values are based on the chi-square test or Fisher exact test for categorical variables and t tests for continuous. Risk level is based on HbA1c, BP, smoking status, alcohol consumption, and depression (PHQ-9 score)
