Correction to:Clinical and Translational Gastroenterology 2021;12(1):e00279. doi: 10.14309/ctg.0000000000000279. Published online: December 22, 2020.

The original version of this article contained an error in Figure 1b (and the corresponding sensitivity analyses in the Supplement). Specifically, among persons with a diagnostic colonoscopy at baseline (diagnostic index colonoscopy), the figure shows a mistakenly high proportion of persons with a repeat colonoscopy already in the first quarter after baseline. The error occurred due to diagnostic colonoscopies that were partly coded both using an OPS and an EBM code. If these codes had different dates in the data set, the respective colonoscopy was erroneously double-counted, although it was only one examination. The error has now been corrected. The error particularly affected the proportion with a repeat colonoscopy in the first quarter after baseline while the cumulative proportion of persons with a repeat colonoscopy reported in the abstract was less affected (see below). The correction has no impact on the conclusion of the study. For screening colonoscopies, the error did not occur because they are only coded using EBM codes.

The RESULTS section in the ABSTRACT should read: “Among persons with diagnostic index colonoscopies, 76%, 71%, and 55% had a repeat colonoscopy, …” (instead of “80%, 78% and 65% had a repeat colonoscopy,…”) The description of Figure 1b in the RESULTS section of the main article should read: “Among persons undergoing a diagnostic colonoscopy at baseline, the overall patterns were similar, but in cohorts 2 and 3, the cumulative proportions with at least one repeat colonoscopy were higher compared with those with a screening colonoscopy at baseline (71% and 55% within 10 years, respectively) (Figure 1b).” The DISCUSSION of Figure 1b should be shortened to “Regarding persons undergoing a diagnostic colonoscopy at baseline the overall patterns were similar to persons with a screening colonoscopy,” that is it is obsolete to speculate on reasons of the high proportion of persons with a diagnostic index colonoscopy undergoing an early repeat examination.
