Table 1.
Characteristics of patients with prostate cancer and matched controls.
| Characteristic | Patients (n = 217) | Controls (n = 1080) |
|---|---|---|
| Age in years at diagnosis | n (%) | n (%) |
| <60 | 15 (7) | 79 (7) |
| 60–69 | 51 (24) | 253 (23) |
| 70–79 | 100 (46) | 494 (46) |
| ≥80 | 51 (24) | 254 (24) |
| Number of consultations per patient | Median (IQR) | Median (IQR) |
| In the 2 years | 14 (10–21) | 10 (5–17) |
| Excluding last 180 days | 9 (5–14) | 7 (4–13) |
| Number of ICPC codes per patient | Median (IQR) | Median (IQR) |
| In the 2 years | 28 (18–42) | 18 (9–32) |
| Excluding last 180 days | 17 (9–28) | 13 (7–24) |
For all the summary consultation and code measures there was strong evidence of higher occurrence in cases than controls: over the whole 2 years P<0.001 for both measures. This was not so once the last 180 days were excluded from analysis: P = 0.41 for consultations, P = 0.12 for codes (Mann–Whitney U test).
IR = interquartile range.
ICPC = International Classification of Primary Care.
