A prepackaged low\u2010residue diet (PLRD; Clear\u2010Through) may improve bowel cleansing and allow further PEG reduction.

The primary endpoint was cleansing quality using the Ottawa Bowel Preparation Score (OBPS). Secondary endpoints included bubble score, bowel movement frequency, adherence, tolerability, patient satisfaction compared with the previous colonoscopy, and adverse events. Logistic regression identified predictors of inadequate cleansing.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Baseline characteristics were comparable across groups.
