a
As compared with reference group BMI 18.5 to 25.
b
Adjusted for factors relevant to the allocation system, factors possibly influencing access to health care, and center-specific clustering.
c
Adjusted for factors relevant to the allocation system, factors possibly influencing access to health care, factors biologically related to disease progression and outcomes that could influence provider risk–benefit decisions, and center-specific clustering.
