  1. The control population was matched by sex, birth year and year of first hospitalisation/access to LSS services to individuals with ID. The total follow-up period for individuals with ID was 190,788 person-years, and for the control population was 1,032,245 person-years. The adjusted mortality rate ratio was obtained using conditional fixed-effects Poisson regression
