Stegomyia indices and PPI in three SES zones (ward N = 12), Dhaka, 2011
| SES zone | HI* | 95% Confidence interval | CI* | 95% Confidence interval | BI* | 95% Confidence interval | Number of collected pupae | PPI |
|---|---|---|---|---|---|---|---|---|
| LSESZ (5 wards) | 25.3 | (16.8–33.8) | 37.6 | (28.1–47.1) | 62.9 | (53.4–72.4) | 107 | 0.53 |
| MSESZ (5 wards) | 20.6 | (12.6–28.5) | 31.2 | (22.1–40.3) | 52.0 | (42.2–61.7) | 169 | 0.55 |
| HSESZ (2 wards) | 18.6 | (11.0–26.2) | 28.8 | (19.9–37.7) | 63.4 | (53.9–72.8) | 271 | 0.62 |
| All SES zones | 26.7 | (23.6–29.7) | 32.8 | (30.4–35.2) | 59.6 | (56.3–62.9) | 547† | 0.58 |
BI = Breteau index; CI = container index; HI = house index; HSESZ = high SES zone; LSESZ = low SES zone; MSESZ = medium SES zone; PPI = pupae-per-person index; SES = socioeconomic status.
*
See Section Materials and Methods for definitions of these indices.
†
Three pupae become adults during the transfer from the field to the laboratory.
