Multivariate analysis of the estimated effect of HIV on parasitemia risk at different time points and over follow-up
| Primigravidae | Multigravidae | |||||
|---|---|---|---|---|---|---|
| Fraction parasitemic (%) | Prevalence ratio (95% CI) | Fraction parasitemic (%) | Prevalence ratio (95% CI) | |||

| Enrollment | 10/23 (43.5) | 186/316 (58.9) | 0.85 (0.34–2.12) | 60/162 (37.0) | 179/865 (20.7) | 2.28 (1.58–3.28) |

Models adjusted for education, maternal weight, bed net use, and number of SP doses received.

Excludes enrollment visit, risk ratio.
†
Primigravidae weighted generalized estimating equations (wGEE)1 results not reported because of sparseness of data across visits, average risk over follow-up, frequencies vary according to visit.
