Evening pain intensity (NRS) reported in the diary; before, during and after the provocation. The figure shows model based means (EM means) of pain intensity (NRS), from the regression analysis. The dotted grey lines represents EM means ± standard error. The interaction time*group were not statistically significant (p = 0.2738) and hence the development of pain intensity over time were not proven to be different for the two groups
