Statistically significant interaction on risk of DM was observed between RETN - 420 G / G genotype and BMI < 25 ( OR for interaction = 0 . 12 ; P = 0 . 046 ) , and when subjects with RETN - 420 C / C + C / G and BMI >= 25 ( n = 69 for DM and 544 for non - DM ) were defined as the reference , the adjusted ORs for subjects with RETN - 420 G / G genotype and BMI > 25 ( n = 10 for DM and 111 for non - DM ) , RETN - 420 C / C + C / G and BMI < 25 ( n = 81 for DM and 1 , 605 for non - DM ) , and RETN - 420 G / G and BMI < 25 ( n = 1 for DM and 230 for non - DM ) were demonstrated to be 0 . 72 ( 95 % confidence interval : 0 . 36 - 1 . 46 ) , 0 . 40 ( 0 . 28 - 0 . 56 ) and 0 . 03 ( 0 . 005 - 0 . 25 ) , respectively .
