Types of cancer diagnoses included esophageal cancer (EC), gastric cancer (GC), and colorectal cancer (CRC). Purified UBE2E3-GST protein, DAN-GST protein, and antigenic SOSTDC1 peptide were used as antigens. Cutoff values were determined as the average HD values plus two SDs. P values were calculated by comparing the results of HDs and patients using the Kruskal–Wallis test. P values < 0.05 and positive rates > 10% are marked in bold. A scatter dot plot of the same results is shown in Figure 1EG. DAN-Ab: anti-differential screening-selected gene aberrant in neuroblastoma antibody
