Basic ADL (BADL) and instrumental ADL (IADL) were assessed using the Barthel Index and the Lawton and Brody IADL scale, respectively. Rectal stool attenuation, rectal lumen area, stool area, and gas area were measured on the axial slice with the largest rectal cross\u2010section. High\u2010attenuation stool was defined as &gt;\u2009100 HU, and 10\u2009cm\n                      <jats:sup>2<\/jats:sup>\n                      was used as the threshold for rectal area parameters. Correlations between continuous CT parameters were examined using Spearman's rank correlation. Associations between CT findings and ADL were first examined by comparing mean ADL scores between groups defined by CT parameters; multivariable logistic regression was then used to evaluate factors independently associated with high\u2010attenuation stool. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Among 116 participants (mean age, 85.8\u2009years), 31.0% had high\u2010attenuation stool. High\u2010attenuation stool was associated with significantly lower BADL scores (55.4\u2009\u00b1\u200938.0 vs. 74.4\u2009\u00b1\u200927.5) and IADL scores (2.4\u2009\u00b1\u20092.9 vs. 3.9\u2009\u00b1\u20092.8). Stool attenuation was positively correlated with stool area (\n                      <jats:italic>r<\/jats:italic>\n                      \u2009=\u20090.34) and negatively correlated with gas area (\n                      <jats:italic>r<\/jats:italic>\n                      \u2009=\u2009\u22120.31).
