We grouped 463 individuals into the AT user group and 1864 into the nonuser group. Patients in the AT user group were significantly older and more likely to be male. After propensity score matching for age, sex, and Boston bowel preparation scale, the ADR and PDR in the AT user group were significantly lower than those in the nonuser group. Univariate logistic analysis revealed that multiple AT use (odds ratio [OR]: .39, <jats:italic>p<\/jats:italic>\u00a0&lt;\u00a00.001) had the lowest OR for FIT PPV, followed by age\u2010 and sex\u2010adjusted factors for the ADR and any AT use (OR: .67, <jats:italic>p<\/jats:italic>\u00a0=\u00a00.0007). No significant factors related to AT use were observed among age\u2010adjusted predictive factors for invasive CRC, but warfarin use was a borderline significant positive predictive factor (OR: 2.23,
