PHLPP2 and reading: Univariate Cox regression analysis identified 17 genes were associated with the prognosis of READ (Supplementary Table 2 and Table 2), while multivariate Cox regression analysis showed the PHLPP2 gene (downregulated) was the only correlated with the survival outcome of READ (HR = 0.442, 95% CI 0.215-0.906, P = .026; Supplementary Table 2 and Table 2).
