B is a coefficient indicating a one-unit increase in an independent variable in multivariable linear logic regression analyses. “/" indicates that a variable was not significantly associated with LDL-C level in a given model.

BMI, body mass index; LDL-C, low-density lipoprotein cholesterol; yo, years old.
