Adults aged 40 to 79 years who were scheduled for a colonoscopy owing to FIT positivity, symptoms, screening, or surveillance were randomized 1:1 to CAD-assisted or standard colonoscopy. Data were analyzed from December 1, 2024, to February 28, 2025.<\/p>\n\n\n\n<p><strong>Exposures<\/strong>&nbsp;&nbsp;Colonoscopy performed with a real-time CAD system or standard high-definition colonoscopy.<\/p>\n\n\n\n<p><strong>Main Outcomes and Measures<\/strong>&nbsp;&nbsp;The primary outcome was adenoma detection rate (ADR), defined as the proportion of patients with at least 1 histologically confirmed adenoma. Secondary outcomes included adenomas per colonoscopy (APC), sessile serrated lesion detection rate (SSLDR), and postpolypectomy surveillance intervals according to the US Multi-Society Task Force (USMSTF) and European Society of Gastrointestinal Endoscopy criteria.<\/p>\n\n\n\n<p><strong>Results<\/strong>\u00a0\u00a0Of 1356 randomized participants (mean [SD] age, 60.0 [9.4] years; 678 [50.0%] female and 678 [50.0%] male), CAD-assisted colonoscopy met noninferiority criteria for ADR compared with standard colonoscopy (395 of 675 [58.5%] vs 363 of 681 [53.3%]; absolute difference, 5.2 percentage points [95% CI, \u22120.1 to 10.5 percentage points]). Superiority was not statistically significant. CAD significantly increased mean (SD) APC (1.41 [1.95] vs 1.20 [1.88];\u00a0<em>P<\/em>\u2009=\u2009.01), driven mainly by detection of diminutive adenomas. In exploratory analyses of 864 patients with FIT-positive findings, CAD significantly increased ADR (288 of 441 [65.3%] vs 243 of 423 [57.4%];\u00a0<em>P<\/em>\u2009=\u2009.02; adjusted odds ratio [AOR],\u20091.39 [95% CI, 1.05-1.86]) and APC (mean [SD], 1.64 [2.08] vs 1.39 [2.09];\u00a0<em>P<\/em>\u2009=\u2009.01). SSLDR did not differ between groups. Consequently, CAD led to more intensive surveillance recommendations under USMSTF criteria, particularly in patients with FIT-positive findings (58 of 441 [13.2%] vs 31 of 423 [7.3%]; AOR,\u20091.94 [95% CI, 1.22-3.09]).<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/cdn.jamanetwork.com\/ama\/content_public\/journal\/jamanetworkopen\/939815\/zoi260177va_1778505890.25076.png?Expires=1785984585&amp;Signature=KGayrV8RRpL3xH83yiQLbucUpBGut8AIWmuN7f53YnQ9ZP6FJvxOmIZWgvLz8bW8qs1WAQGLh1Fz1sB3OeOZ9Y7tzIZwLtrkUfzNu8-fR8de3Lex6fnN6s6zn0hwdarJjLF8aI~Kx36qMBmG48a7MuN3LfhsElxjUlGqZ604BbHCrkOe-Ma~Mxbiw~Zw7McKUWdgYVs1-mkvgkgncPlsFef9MOiTuIo4Up7trrbnazT-W8I84GZ5teECV~ybmT0i~Te0wUZqyvUTQzyLqCRtkC2jWWyAFYwLhK3XLQTkiLZWU297KLISCJgrB0TJwGdMMZnmx7cIYo~jJfxRG5fz1w__&amp;Key-Pair-Id=APKAIE5G5CRDK6RD3PGA\" alt=\"\"\/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/cdn.jamanetwork.com\/ama\/content_public\/journal\/jamanetworkopen\/939815\/zoi260177f1_1778505890.31318.png?Expires=1785984585&amp;Signature=1uk0~hTyev0Yzg9jMhia30ZgSOME1Q1V95LEnW12y6RQ5~TiXFsS5XaR48NHn20-kDWHyO5~KRRmwRImnDVYs3ThkvmjPiFBNgkMUXb0EKSVm0Bi6HaXUyOPhanifOZTOTgp8zfJlTXOtq0t0neQREG9pDMrrwjAqhH9UnJmWA-zsd3LCZgTQH9ukD3NVST0YEz6vYrC5zwAY6gvva6U~YX4ab1LG2ej4djiVG0csv-B~-61G-Y9liwacn2oUilMJe99865FUaR80RLEXmZjC9jf2O~f1hnY4O2YzmVPY6-9bP-fLVLqUtR0p~5uJPidQr~wHE3CZrkPJsUV1BwqNQ__&amp;Key-Pair-Id=APKAIE5G5CRDK6RD3PGA\" alt=\"\"\/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/cdn.jamanetwork.com\/ama\/content_public\/journal\/jamanetworkopen\/939815\/zoi260177f2_1778505890.45818.png?Expires=1785984585&amp;Signature=xCd43jubMY2Wjv7R9VEg07wgInmuzqRVAymwcaxrhnNZTat-u9n~6rZ35ATu640xxIv59q5f5NIA~~Gal0fwW-T6b21Y-Ppk8AfipGxfrh6FR1mmMEz1z1a6aztlTugWk2V8qDkuWKGHRfwT9osvsjAsqUikPP7tMhc4zXRb3mVF99UoYaibCmD9B4tkszYdmdiJwnz0KZT4LYKJ3X-e9sDkmXjWeAGPGLuz0hSOG3OFfityb-h6xC27ZB2r5xcNyoh~DAiurV6rCityfjyCXfKKEXcXdIjzm1fWG752WIpkZmKx5SF~DD-aC07XBJ1AX7RZesFTO~1ZrrwKMgskuA__&amp;Key-Pair-Id=APKAIE5G5CRDK6RD3PGA\" alt=\"\"\/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/cdn.jamanetwork.com\/ama\/content_public\/journal\/jamanetworkopen\/939815\/zoi260177t1_1778505890.35818.png?Expires=1785984585&amp;Signature=d7UXj4xznMgtLrAd2AdM~pXvd9dulmgpXh2zX2aoJT6Ix~Rh3oXfZViidi9q4yMnlEKgMRZYjVEq4yqVCweq0kHdstmHQn4UcxUNnd5vQKprO1Y61bfW~hBxsVSjP495jGEZimdjb67tAUoWD7WtxuwQA-Qz~3EL2xNZM-h8E3lMDeTR51gR1hI6-kHwZai9z9a0FJwov4RfAnxCVH0fVjKCxmbrOMWVqakiMvuPQhAJm0JFv5XCkXxhKraVxP11TWbC9c8OQgUyCKl-TZpXz9MF5JZVrlbD6Vj-IZB4yrpDNYmIkwC-QcfGX7v74OqbQeuAKibVPO-EIELSJf9eZg__&amp;Key-Pair-Id=APKAIE5G5CRDK6RD3PGA\" alt=\"\"\/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/cdn.jamanetwork.com\/ama\/content_public\/journal\/jamanetworkopen\/939815\/zoi260177t2_1778505890.45318.png?Expires=1785984585&amp;Signature=P989IXsuQABYbrpedW85v-La3JMuSVn6NTHCt~BK1pcrBC8oSKdV3FlQcH-bHI-6fbDU8411o1tc3uc3QPe3GBZjvISULj3TSHGDdOQtd3Meu-pbYpsguB-gc3ZZmeglrdKaBRM8qsG2qPj-7AOz0UuPu52Hhs52ivOXDoMKcWzvv6h9jJb9MuMfg0c6Hn-V3juLAhGCjwPVXQUKFjAm9ViHQi3CutEubHI6XEVFigKAqEypxZswoBvv42Ey1Vi4ixFj90xnT7pHgAwr8loe7XSxcbIL03G-jIs2nxzZ3VIlRX1aNOh7-fDkHAw-uignYjw7ezlIBoUmD5YjsooHoQ__&amp;Key-Pair-Id=APKAIE5G5CRDK6RD3PGA\" alt=\"\"\/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/cdn.jamanetwork.com\/ama\/content_public\/journal\/jamanetworkopen\/939815\/zoi260177t3_1778505890.48818.png?Expires=1785984585&amp;Signature=vOtT1aSdHqKkMJMGBVJRbaL6~EyX~wMkpcsSKAEkPWrKtz~9QhsFrCUeQE1TT4lLwvIAfMR8dt~sv7p2DhE-55~KmZYVLrnSaA64IhnXEklsv~7LnNgflV5OpHNUnJUzmr5H0nDn0eEq8fCYfIF5NrHyjzvPJ1--AxnD1dywAN88i24gpoV3u7yqnIjoeF4Kbep-2RW4oK2AnsdtNM5GPbSN2zkjbdDxq3t37SWtKgGjx99XTI9Q1qHcpaARlOTX6V6oGBMXewwsLuTqXbFf88EiBkYQ1jtfBzQbLZr9Y6USfkLzf0cLISoOLtC~eZp5eREdaIJ1~~WaNMubtwqBKw__&amp;Key-Pair-Id=APKAIE5G5CRDK6RD3PGA\" alt=\"\"\/><\/figure>\n\n\n\n<p><strong>Conclusions and Relevance<\/strong>&nbsp;&nbsp;In this randomized clinical trial, CAD-assisted colonoscopy met noninferiority criteria for adenoma detection.
