Table 4 Legend: Death data obtained included year of death (YOD) and cause of death (COD). Data collected for 1st and 2nd generation immigrants were compared to the data obtained for non-immigrants, and young and middle-aged individuals were compared to the data available for older cohort members (>60 y). (1) Chi-squared contingency; Test, (2) Logistic regression analysis; (**) for p-value < 0.0001; (*) for p-value < 0.05.
