(A) Correlation of S100 and ctDNA. For improved visualisation depicted on a logarithmic scale. On x-axis S100 values (S100 → log10 (S100 + 1)), on y-axis ctDNA values (ctDNA → log10 (ctDNA+1)). Spearman’s ρ test: p-value < 0,0001. (B) Contingency of S100 and ctDNA. Sensitivity = true positive/(true positive + false negative) Specificity = true negative/(true negative + false positive) Accuracy = (true positive + true negative)/(true positive + true negative + false positive + false negative). Prediction value calculations with Fisher’s exact test: S100 not significant, ctDNA p-value 0,0047.
