Three diseases have shown, on average, a decline in SOD for both population categories: cerebrovascular diseases (−2.406% (p > 0.05) and −2.890% (p > 0.05)), ischemic heart diseases (−2.324% (p > 0.05) and −2.044% (p > 0.05)), and blood diseases (−0.356% (p > 0.05) and −0.615% (p > 0.05)). This evidence concerns the gene SOD1 and cerebrovascular disorder.
