Circulating SPARC evaluation as a diagnostic and prognostic marker. a ROC curve of SPARC evaluating the capability of SPARC levels to discriminate between lung cancer patients and controls, with AUC and its bootstrap 95% CI. The optimal cutoff and sensitivity and specificity corresponding to the optimal cutoff of the ROC are reported. b Kaplan Meier overall survival (OS) curves for SPARC levels divided into three categories (≤1st tertile, 1st-2nd tertile, >2nd tertile) on the entire case series. c Kaplan Meier OS curves for SPARC levels divided into three categories (≤1st tertile, 1st-2nd tertile, >2nd tertile) on stage I-II patients, p = log-rank test p-value
