Table 7. A multiple linear regression model for the concentration of 6-TGN.^a .

Parameter		Estimate	95% CI	P
Intercept		0.08	−0.16–0.31	0.52
TUSC2		−0.27	−0.46–−0.07	0.008
Glucocorticosteroids	Yes	−0.22	−0.41–−0.04	0.02
5-ASAxGlucocorticosteroids	Yes	−0.11	−0.25–0.03	0.14

^aThe regression model is based on the expanded patient cohort (n = 54), using the natural logarithm of the 6-TGN concentration as dependent variable and the gene expression level (dC_T value) of TUSC2, and glucocorticosteroid and 5-ASA therapy as independent variables. A higher dC_T value is associated with a lower gene expression level. R² = 0.27, P = 0.001.
