Table I.
Distribution of patients in four diagnostic subgroups.
| MDE | Denmark | Finland | Sweden | Norway |
| % (95% CI) | % (95% CI) | % (95% CI) | % (95% CI) | |
| True positives | 3.1 (2.5–3.6) | 3.0 (1.8–4.1) | 3.3 (2.2–4.3) | 2.7 (1.8–3.6) |
| False positives | 12.4 (11.2–13.5) | 16.4 (13.8–19.1) | 15.3 (13.0–17.6) | 25.2 (22.3–28.0) |
| True negatives | 82.1 (80.7–83.5) | 79.1 (76.0–82.2) | 80.1 (77.6–82.6) | 71.3 (68.3–74.3) |
| False negatives | 2.5 (2.0–2.9) | 1.5 (0.8–2.3) | 1.3 (0.7–2.0) | 0.9 (0.4–1.3) |
| Patients in total | 4.271 | 1.180 | 1.283 | 1.720 |
Notes: The four diagnostic subgroups were defined on the basis of patients' DSQ results and GPs' MDE diagnoses for Denmark, Finland, Sweden, and Norway respectively. The numbers represent proportion (%) of patients classified in each subgroup out of the total number of patients in each country. Parentheses represent 95% confidence intervals. The 95% confidence intervals were adjusted for GP clusters (correlation between the multiple judgements from each GP).
