a
Higher SF-36 scores indicate better quality of life, with a population average set to 50.
b
t(651)=−4.35, p<.001
c
F(4, 647)=4.91, p<.001; Post hoc tests showed that scores were worse for 45–54 year olds compared to the two youngest age categories (i.e., 18–24 and 25–34)
d
t(530.2)=12.59, p<.001
e
t(651)=4.65, p<.001
f
t(651)=10.56, p<.001
g
t(651)=12.25, p<.001
