Table 6 Baseline predictors of response shift

From: How are you? Do people with inflammatory bowel disease experience response shift on this question?

Ā 

Negative (nā€‰=ā€‰31) v no RS (nā€‰=ā€‰294)

Positive (nā€‰=ā€‰23) v no RS (nā€‰=ā€‰294)

Ā 

Odds ratio (95% CI) [per unit of predictor]

Mean (RS-) versus mean (RS 0 ) (pooled SD) p-value of the difference in means
