As shown in KM survival graphs, low PTPN6 expression correlates with inferior OS not only in all PTCL patients all together (HR = 0.97, p = 0.89), but also when PTCL-NOS and AITL patient cohorts were analyzed separately (Fig. 4a–c). This evidence concerns the gene PTPN6 and angioimmunoblastic T-cell lymphoma.
