Following publication of the original article, it was identified that there was an error in reporting the sample size calculation. The non-inferiority margin was inaccurately reported as -0.5%, whereas it should be correctly stated as -8.0%. The stated − 0.5% refers to the clinically acceptable difference in the context of the national screening program guideline, which require that a minimum of 90% of the participants achieve adequate bowel preparation. Given this clinically acceptable difference of -0.5%, corresponding to at least 89.5% of the participants achieving adequate bowel preparation, and the current adequate bowel preparation rate of 97.5%, the correct non-inferiority margin is -8.0%.
Importantly, the error is only in the wording of the sample size description. There is no alteration to the total number of inclusions, as the calculation was based on the correct non-inferiority margin of 0.08. Therefore, the integrity of the study’s design and its conclusions remain intact.
