Supplementary Material for: Estimation of invasion depth of early colorectal cancer using Endoscopic ultrasonography and Magnifying chromoendoscopy: a meta-analysis

Introduction magnifying chromoendoscopy (MCE) and Endoscopic ultrasonograpty (EUS) are often used as diagnostic tools to estimate the depth of invasion in early colorectal cancers (CRCs). The aim of this study was to compare MCE with EUS in distinguishing between slight submucosal invasion (invasion depth

引言：放大染色结肠镜检查（MCE）和内镜超声检查（EUS）通常被用作诊断工具，以评估早期结直肠癌（CRC）的侵袭深度。本研究旨在比较MCE与EUS在区分轻微黏膜下侵袭（侵袭深度）方面的差异。
