Singla M, Hutfless S, Al Kazzi E, et al. Clinical codes combined with procedure codes increase diagnostic accuracy of Crohn’s disease in a US military health record. BMJ Open Gastro 2020;7:e000378. doi:10.1136/bmjgast-2020-000378

This article was previously published with errors which have now been corrected by the authors. The corrections are listed below:

(1) Data referred to in the last paragraph of the ‘Results’ section did not match that in Table 1. The text has been corrected to match Table 1.

(2) ORCID id and middle initial of senior author (Dr Brant) have been added and his affiliations has been corrected.

(3) Affiliation 7 has been updated as ‘Division of Gastroenterology and Hepatology, Crohns and Colitis Center of New Jersey, Rutgers Robert Wood Johnson Medical School, New Brunswick, New Jersey, USA’.

(4) Affiliation 8, ‘Department of Genetics, Rutgers University, Piscataway, New Jersey, USA’ has been added to Dr Brant.

(5) ‘Specificity’ has been emphasized and corrected in the Abstract and the Summary Box as it is more universally used and is less tied to a specific data set than the ‘positive predictive value (PPV)’ (which was mainly emphasized alone).

(6) Edits have been made in the ‘Conclusions’ of the Abstract and to the ‘Summary Box’ with appropriate deletions.to more clearly reflect the main points of the study.

(7) Abstract has been updated accordingly to match that in Table 1 as above.

(8) In the first paragraph of ‘Results’ section, the IBS number has been updated to 16, and ‘small bacterial overgrowth’ has been updated to ‘small bowel obstruction’. This now reads ‘commonly IBS (n=16), small bowel obstruction (n=1)’.

(9) Edits have been made to the summary statement in the first sentence of the second paragraph of the ‘Discussion’ to more clearly reflect on the study and for clarity.

(10) Table 1 footnote, ‘Diagnostic accuracy, Sensitivity, Specificity and Positive predictive value are in percent.’ has been added.

(11) The supplement Table has been included.
