GSTM1 and stroke disorder: For the influence of rehabilitation therapy on biomarkers in peripheral blood in stroke patients, the meta-analysis revealed a low-quality evidence that the concentrations of superoxide dismutase (SOD) (17, 19, 27, 42), albumin (ALB) (31, 32, 37), hemoglobin (HB) (20, 22, 31, 37), and catalase (CAT) (17, 19, 42) significantly increased in peripheral blood in the treated group, and that this was significantly associated with improvement in function after stroke (Supplementary Figures S10–S13; Table 1).
