^aIn Steps 2 and 3, only the newly included variables are presented.

^bAge was measured in categories and therefore has been included as a dummy variable. The category with the highest n (age: 45-54 years, n=70) was used as a reference. For β, B, and T minima, the maxima of each group contrast are presented. The P value was aggregated using the statistical software R; no single P value of each contrast reached statistical significance.
