There is an error in the second sentence of the Results section of the Abstract. The correct sentence is: According to the Newcastle-Ottawa Scale (NOS), eight papers were considered high quality.

There is an error in the third sentence of the Results section of the Abstract. The correct sentence is: After the data of these 10 studies were combined, an increased risk of CRC was found among the individuals who had undergone cholecystectomy (risk ratio (RR) 1.22; 95% confidence interval (CI) 1.08–1.38).

There is an error in the last sentence under the heading “Literature search and study characteristics” in the Results section. The correct sentence is: The NOS scores for 8 of the included articles were ≥ 7.0, indicating high quality.

There is an error in the fourth sentence of the Discussion section. The correct sentence is: But, contrary to Chiong’s study [41], no relationship between cholecystectomy and RC was found in our study.
