Contingency table comparing results of tumor-informed and tumor-type informed approaches for ctDNA detection. In the tumor-informed approach, samples are classified as ctDNA-positive when at least 2 tumor-SNVs with a p-value < 10^− 3 are detected. For the tumor-type informed approach, samples are classified as ctDNA-positive if the predicted value from the SVM classifier is positive
