N/A - Not Available

Significant difference at p <= 0.05

^†

Number of cases too low for the analysis

Underlined Significance is in hypothesized direction

All analyses were adjusted for age, sex, and Charlson comorbidity index. A value of 1.0 indicates a null effect. See text for interpretation.
