Notes: Data are expressed as mean±standard deviation; P value was determined by one-way ANOVA tests or Tukey’s test; aIndicates patients with NPC vs. those with benign tumors of the nasopharynx: P<0.05 (Tukey’s test); bIndicates patients with benign tumors of the nasopharynx vs. healthy subjects: P<0.05 (Tukey’s test); cIndicates patients with NPC vs. healthy subjects; P<0.05 (Tukey’s test).
Abbreviations: WBC, white blood cells; RBC, red blood cells; M, monocytes; L, lymphocytes; N, neutrophils; PLT, platelets; MPV, mean platelet volumes; MPV/PC ratio, mean platelet volume/platelet count ratio; PDW, platelet distribution width.
