For all these measurements, QCIGISH was generally more sensitive [100.0% for < 2 cm (significant at p = 0.023 for WCC) and 100.0% for 2–3 cm (marginally significant at p = 0.134 for WCC)] than cytology and small biopsy pathology (66.7% for < 2 cm and 87.5% for 2–3 cm), although their specificities were relatively comparable (Fig. 5 C, D, Additional file 2 : Table S16 and S17).
