Adjusted for age, sex, and race and ethnicity. In pairwise comparisons (across row), cells with common superscript do not differ significantly (at P < .05).
a
For given group, tabled n represents approximate midpoint from range of analytic n over all variables.
b
Composite risk score is based on 14 binary (0,1) indices, reflecting lower-risk versus high-risk status for each row variable in table.
