Correlation analysis of experimental indicators of 180 patients with nasopharyngeal cancer.

Indicators	Hb/RDW (P/r)	NLR (P/r)	PLR (P/r)
Hb/RDW	∗	0.039/−0.154	0.039/−0.154
NLR	0.039/−0.154	∗	0.000/0.704
PLR	0.039/−0.154	0.000/0.704	∗
Stage	0.152/−0.107	0.043/0.151	0.425/0.060
Serosal invasion	0.184/−0.100	0.055/0.143	0.031/0.161
Lymph node metastasis	0.302/−0.077	0.030/0.162	0.314/0.075
Distant metastasis	0.064/−0.138	0.002/−0.232	0.002/−0.227

P value was calculated by the Pearson or Spearman correlation analysis. The r value indicates the degree of correlation between the two related indicators.

Hb/RDW = hemoglobin-to-red cell distribution width ratio (Hb/RDW), NLR = neutrophil-to-lymphocyte ratio, PLR = platelet-to-lymphocyte ratio.

^∗ Indicates that there is no correlation between the 2 indicators.
