The data were analysed in 2021. The \u2018PheWAS\u2019 R package was used to perform the PheWAS analyses and Bonferroni correction was used to adjust for multiple testing.

The 29 dermatological and 12 oral disorders were often highly enriched, whereas hepatic, gastric, oesophageal and intestinal PheCodes displayed ORs in the range of 1\u00b76\u20134\u00b75.
