ESR1 and chronic neutrophilic leukemia: The pathological subtype, FIGO stage, ER, PR, HbA1c, and HDL-C were included in the univariate and multivariate Cox regression model analysis (Table 2), in the multivariate Cox analysis, the pathological subtype (HR 0.053, 95% CI 0.008–0.363), PR (HR 0.969, CI 0.945–0.994), and HDL-C (HR 0.059, CI 0.005–0.646) were statistically different, thus the three factors were independent risk factors for prognosis in the CNL group.
