Preoperative serum basophil count and the corresponding hazard ratios on a continuous scale, including (a). DFS before adjusting for other prognostic factors; (b). DFS after adjusting for other prognostic factors; (c). OS before adjusting for other prognostic factors; (d). OS after adjusting for other prognostic factors. Analyses were conducted using restricted cubic splines, with hazard ratios and 95% confidence intervals from univariate to multivariate Cox proportional hazards regression. The basophils count of 0.03*109/L was chosen as the reference. The purple area indicated the distribution of concentration of the basophils count
