When comparing protein accession numbers between the models without taking proteoforms into account, several models shared the same type of protein, but not the same proteoforms (i.e., as indicated by spot number), e.g., fibrinogen beta chain was present in all models and hemopexin was present in the models of pain intensity, PPT, and psychological distress in FM (Fig. 9b). The gene discussed is HPX; the disease is Abnormal emotional state.
