^*Linear regression model with dependent variable = PASE score. Model adjusts for age. Independent variable = tertile (including all three tertiles).

^**Linear regression model with dependent variable = PASE score. Model adjusts for age. Independent variable = tertile (only including highest vs. lowest tertile).
