Table 3 Relative risks (RRs) with 95% confidence intervals (CIs) for prescription among people with intellectual disability (ID) compared with a referent cohort from the general population (gPop) and for demographic factors within the ID cohort, stratified by diagnoses of mood disorders (F32-F39 in ICD-10) and/or anxiety (F4). Bold indicates statistically significant differences in prescription
