One study22 reported the association of SLCO1B1 genotypes with myalgia and CK elevation separately from the same population group, so we just extracted the data based on CK elevation, because most existing definitions of statin-related myopathy were based on biochemical standards rather than clinical phenotypes.27 Valid genotyping methods were applied throughout all the studies. The gene discussed is SLCO1B1; the disease is myopathy.
