Forest plot of primary care to hospital inpatient data prevalence ratios. Prevalence ratios are calculated by dividing prevalence using only primary care (PC) data by prevalence using only hospital inpatient (HI) data: PC/HI ratio. Error bars represent 95% confidence intervals. The vertical dotted line represents where the PC/HI ratio is 1, meaning the prevalence rate is the same using both PC and HI data. Where the ratio is > 1, the prevalence was higher using PC versus HI data. Conversely, a ratio < 1 represents conditions where prevalence is higher using HI versus PC data. Conditions are grouped by ICD-10 chapter
