In 2015, I included fibromyalgia patients based on 2011 diagnostic criteria. the project was left for the last four years because of personal issues. now we have 2016 Revised criteria. and there is no way to reach the patients again in order to update the data. Can i proceed in the project now by the same data ( Iam writing the manuscript now) ?
or the data are no longer valid ?
what should I do ??
