a
Factor upon which subgroup analysis was based.
b
Significance probability associated with the test of the null hypothesis that subgroups defined by the specified moderating factor did not differ in treatment effect.
c
.05 < p < .10; possible suggestive result.
d
p ≤ .05; however, result did not remain significant after adjustment for multiple comparisons.
