^aFor Asians with acute lymphoblastic leukemia (13/14) versus Asians with all other diseases combined (31/58), χ² = 7.37 and P = 0.007; for Asians with acute lymphoblastic leukemia (13/14) versus whites with acute lymphoblastic leukemia (34/88), χ² = 14.3 and P < 0.001; for Asians with acute lymphoblastic leukemia (13/14) versus Hispanics with acute lymphoblastic leukemia (16/41), χ² = 12.1 and P < 0.001; for Asians with acute lymphoblastic leukemia (13/14) versus blacks with acute lymphoblastic leukemia (3/7), P = 0.025 (by Fisher exact test).

^bNS, not significant.

^cFor whites with myeloma (15/30) versus those with all other diseases (328/911), relative risk = 1.39, χ² = 2.46, and P was not significant.

^dFor Hispanics with myeloma (6/8) versus those with all other diseases (84/212), relative = 1.89, χ² = 3.99, and P = 0.046.
