IQR = interquartile range.
Statistically significant associations (P <0.05) listed in bold.
OR is the odds of having a lower (better) PSI, comparing those in the lowest and highest quartiles of HL scores.
*
Final adjusted model reflects corrected OR after removing non-significant variables. Adjusted model includes age, sex, and race/ethnicity.
