Patient inclusion lasted between 1977 and 2018. Study endpoints were compared between elderly- and adult-onset (AO) patients and different therapeutic eras.

The proportion of EO CD and UC patients was 6.1% (58\/946) and 13.4% (183\/1370) in the total cohort. Biological therapy exposure was significantly lower in EO CD compared to AO [pLogRank\u2005=\u20050.003], but similar exposure was seen amongst UC patients [pLogRank\u2005=\u20050.770]. Early surgery rates (\u22641 year from diagnosis) were significantly higher in EO CD patients compared to AO (27.6% vs 15.6%; P\u2005&amp;lt;\u2005.001). However, there was no statistically significant difference in overall resective surgery rates between the EO and AO cohorts in CD [pLogRank\u2005=\u20050.838], nor colectomy rates differed in UC [pLogRank\u2005=\u20050.435].
