| Parous rate (%) (95% CI) | 57.24 (55.67–58.79) | 35.97 (31.23–41.00) | 36.26 (31.34–41.48) | 28.49 (22.27–35.65) | 47.19 (39.99–54.51) | |
| Mayo Oulo | No. dissected (No. parous) | 1,184 (387) | 136 (52) | 60 (19) | 12 (3) | 925 (328) |
| Parous rate (%) (95% CI) | 32.69 (30.07–35.41) | 38.24 (30.50–46.62) | 31.67 (21.31–44.23) | 25.00 (8.89–53.23) | 35.46 (32.44–38.60) | |
| Total | No. dissected (No. parous) | 7,159 (3,359) | 952 (361) | 678 (211) | 253 (70) | 1,183 (437) |
| Parous rate (%) (95% CI) | 46.92 (45.77–48.08) | 37.92 (34.89–41.04) | 31.12 (27.75–34.70) | 27.67 (22.52–33.48) | 36.94 (34.24–39.73) |
Note: The difference in parity rate between health districts and anopheline species was not significant (χ 2 = 6.62, df = 8, P = 0.58)
