IL6 and non-small cell lung carcinoma: In multivariate logistic regression model analysis, RHR > 82 b.p.m [OR (95% CI), 3.143 (1.092-9.045), p = 0.034], serum sodium ≤ 138.2mmol/L [OR (95% CI), 6.806 (2.488-18.617), p < 0.001] and IL-6 > 6.74pg/ml [OR (95% CI), 3.203 (1.101-9.320), p = 0.033] were independent predictors of declined HRV in newly diagnosed NSCLC patients (Table 3).
