Convergent Validity
When controlling for age and sex, UCT scores strongly correlated with
CDLQI scores in CU (r=-0.74, P<0.01) and CSU (r=-0.72,
P<0.01). A moderate correlation was observed in patients aged
4 to 16 years (r=-0.67, P<0.01). We were unable to assess the
convergent validity of the UCT in CIndU patients because of inadequate
sample size (N<25).
