Comparison of blood inflammatory markers between bacteria-infected subgroup A and TF subgroup A in NNLCPs.
| Variable | Bacteria-infected subgroup A (N = 69) | TF subgroup A (N = 56) | p value Mann–Whitney |
|---|---|---|---|
| PCT median (range) (ng/mL) | 0.24 (0.04, 18.62) | 0.05 (0.02, 1.58)a | <0.0001 |
| CRP median (range) (mg/L) | 53.2 (0.6, 358.3) | 6.3 (0.2, 89.4) | <0.0001 |
| WBC median (range) (109/L) | 8.49 (1.1, 42.54) | 5.24 (1.89, 15.82) | <0.0001 |
| NEU median (range) (109/L) | 7.39 (0.73, 41.32) | 3.56 (0.96, 13.94) | <0.0001 |
| NLR median (range) | 12.15 (1.03, 189.80) | 3.27 (0.69, 39.00) | <0.0001 |
aNot to overestimate possible differences between the two groups, the values reported as <0.02 by the laboratory were noted as “0.02” for statistical analysis. NNLCPs: nonneutropenic lung cancer patients; TF: tumor fever; PCT: procalcitonin; CRP: C-reactive protein; WBC: white blood cell; NEU: neutrophil; NLR: neutrophil-to-lymphocyte ratio.
