CRP and interstitial lung disease: Univariate analysis also showed that there was 6-month OS in larger proportions of patients with white blood cell (WBC) count < 10 000/μl (90.6 vs 44.4%; P = 0.000358), patients with CRP < 0.3 mg/dl (96.6 vs 70.7%; P = 0.0202), patients with percent vital capacity (%VC) ≥80% (94.1 vs 85.7%; P = 0.00569), patients without positron emission tomography (PET) uptake in the ILD lesion (96.3 vs 72.5%; P = 0.0494) and patients who received definitive radiotherapy (98.0 vs 100.0%; P = 0.000127 × 10−13).
