PROM1 and human granulocytic anaplasmosis: As for HGA patients, univariate Cox's regression showed that higher CD133 expression (P = .005, HR = 1.731) and higher Nestin expression (P = .037, HR = 1.440) were correlated with shorter OS, while radiotherapy (P = .018, HR = 0.445) and immunotherapy (P = .026, HR = 0.254) were correlated with longer OS, whereas age (>40 vs ≤40 years) (P = .259, HR = 1.409) and gender (male vs female) (P = .089, HR = 1.785) were not predictive factors for OS in HGA patients (Table 5).
