A borderline significance was found when testing the interaction between race/ethnicity and BMI ( p = 0.063 for interaction), while no clear effect modification was found between race/ethnicity and EOSS ( p = 0.135 for interaction); upon stratification, an apparent neutral effect of BMI categories on all-cause mortality was observed among non-Hispanic Black subjects in contrast to other ethnicities ( Table 5 ). 3.3.
