Table 3 Comparing the coefficients of malaria incidence rates between MDA + IRS and IRS arms among under five years and above five years from July 2015 to May 2019
Malaria incidence rate | < 5 years | ≥ 5 years | ||
|---|---|---|---|---|
Coefficient (95% CI) | P-value | Coefficient (95% CI) | P-value | |
Malaria incidence rate at beginning of study | 84.47 (64.96, 103.99) | < 0.001 | 69.99 (59.63, 80.35) | < 0.001 |
Pre intervention trend of malaria incidence rate from July 2015 to November 2016 | 2.31 (0.28, 4.33) | 0.026 | 1.82 (0.47, 3.17) | 0.009 |
Reduction in malaria incidence rates at month 18 on implementing MDA + IRS compered to IRS | −71.82 (−96.56, −47.09) | < 0.001 | −56.73 (−76.11, −37.35) | < 0.001 |
Trend in malaria incidence rate after implementing intervention: | −3.23 (−5.·24, −1.23) | 0.002 | −2.56 (−4.00, −1.12) | 0.001 |
Difference in malaria incidence rate during interventions between MDA + IRS and IRS arms months after initiation of the interventions | 6.85 (2.53, 11.19) | 0.002 | 6.02 (3.07, 8.98) | < 0.001 |
