Observations and predictions on relationship 3: patient-occupancy ratio when patient data is given. Observed (indicated by circles) and predicted (indicated by diamonds) ratio \(\text{r}\) and occupancy number \({\text{n}}_{\text{o}\text{c}\text{c}\text{u}\text{p}}={\text{n}}_{\text{p}\text{a}\text{t}}/\text{r}\) on the basis of the matched data set and the model of Sect. 2.3.3 for the unmatched EHR dataset, respectively. Observations/predictions of different centres are indicated by the colours of the small dots inside the circles/diamonds, which are coloured with respect to the type of centre (REC: black, REG: blue). Analogous figures with 95% confidence intervals for the observed estimates/predictions can be found in Appendix A.4 (compare Figure A2)
