Table 2 Statistical Analysis of 3 Biomarkers for Screening Patients With Nasopharyngeal Carcinoma Versus Healthy Controls

From: SELDI-TOF MS profiling of serum for detection of nasopharyngeal carcinoma

  Intensity, mean ± SD  
Protein peaks, m/z Noncancer normal NPC P
3159.835 2.13 ± 1.44 1.22 ± 1.04 0.017728
5187.656* 2.00 ± 1.31 1.38 ± 0.60 0.094881
13738.6 0.86 ± 0.54 1.31 ± 0.60 0.002791
  1. SD indicates standard deviation; m/z, mass-to-change ratio; NPC, nasopharyngeal carcinoma.
  2. *The peak is necessary for Decision Tree although the P value > 0.05.
