The number of participants needed to screen (PNS) to detect one ACN case was only 3 in the high\u2010risk group, compared with 25 in the low\u2010risk group, thus demonstrating markedly improved screening efficiency.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>\n                      This study develops and internally validates a risk prediction model for ACN that integrates gastric\u2010related indicators, with\n                      <jats:styled-content style=\"fixed-case\">\n                        <jats:italic>H. pylori<\/jats:italic>\n                      <\/jats:styled-content>\n                      infection as the key predictor.
