| Pre-intervention coverage | Post-intervention coverage | DID (95% CI) | p-valueb | |||||
|---|---|---|---|---|---|---|---|---|
| Adjumani (%) | Moyo (%) | Difference (p-value)a | Adjumani (%) | Moyo (%) | Difference (p-value) a | |||

IPTp: intermittent preventive treatment for malaria in pregnancy; IPT1: first dose of IPTp; IPT2: second dose of IPTp; IPT3: third dose of IPTp; IPT4+: fourth (or higher) dose of IPTp; DID: difference-in-difference; CI: confidence interval.
ap-values relate to the difference in average coverage between the two districts for a given dose of IPTp.
bp-values relate to the difference-in-difference between the two districts for a given dose of IPTp.
*indicates p value ≤0.05.
