An anchor-based method was used to determine the MCIC, with the external criterion (anchor) being based on general perceived improvement (\u2018much improved or very much improved\u2019 on a 7-point Likert scale) in combination with 50% reduction in headache days. Using receiver operating characteristic (ROC) curve analysis we defined an optimal cut-off score discriminating between improved and not improved participants.<\/jats:p>\n
