Hierarchical regression models predicting the number of territorially treated RA patients.
| GDP | GDP + physicians | GDP + rheumatologists | |
|---|---|---|---|
| R 2 | 0.434 | 0.656 | 0.901 |
| F | 30.6 | 37.3 | 177.9 |
| p R 2 | <0.001 | <0.001 | <0.001 |
| R 2 change | - | 0.223 | 0.468 |
| p R 2 change | - | <0.001 | <0.001 |
| B | 93.1 | 72.1 | −3.7 |
| p B | <0.001 | 0.203 | 0.718 |
Notes. GDP was expressed per 1000 €/capita/county; the number of physicians was expressed per 1000 inhabitants/county; the number of rheumatologists was expressed per county; there are 2 models: model 1 (GDP at the first step, GDP and physicians at the second step); model 2 (GDP at the first step, GDP and rheumatologists at the second step). GDP: gross domestic product; RA: rheumatoid arthritis.
