GSTM1 and Stroke: A Kaplan-Meier survival analysis demonstrated shorter overall (Log Rank: p = 0.059) and cardiovascular survival (Log Rank: p = 0.043) as well as shorter time to death of MI (Log Rank: p = 0.235) or stroke (Log Rank: p = 0.038) after the initiation of dialysis in patients who were homozygous for GSTM1-null alleles in comparison with carriers of at least one active GSTM1 allele (Figure 1).
