Reduction in number of days and GPE stratified by expected benefit index. Left side: The mean change in number of days with headache (upper panel) and the mean GPE (lower panel) stratified by treatment group and four subgroups of patients defined by the Expected benefit index. Right side: Estimated treatment effects (reduction in mean number of days with headache by chiropractic treatment (upper panel) and reduction in GPE) at two selected values of the Expected benefit index. The estimates are based on a model assuming a linear change of the treatment effect in dependence on the values. Interactions refer to the difference in reduction between the two selected values. Positive interactions indicate a more distinct advantage of chiropractic manipulation in case of the second (larger) value selected
