Table 4.

Multiple logistic regression to predict whether respondent has visited an HCP about CeD in last 5 years (assuming he or she was diagnosed at least 5 years ago)

	Coefficient	Std. error	P-value
Age group	0.081	0.049	0.098
CDAT score	−0.56	0.16	3.6*10−4
CSI score	0.45	0.13	4.2*10−4
CD-QOL score	−0.38	0.096	5.8*10−5

Positive coefficient means that as age or score increases, probability of visiting an HCP increases. Coefficients and standard errors for CDAT, CSI, and CD-QOL are normalized by the number of questions in the instrument. A higher CD-QOL corresponds to better quality of life, whereas higher CDAT and CSI scores correspond to worse dietary adherence and disease-specific symptoms, respectively
