Prevalence of malaria during pregnancy and coverage of intermittent preventive treatment with sulfadoxine-pyrimethamine in urban Amboasary-Sud, Southern Madagascar.
Article in Malaria journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundMalaria in pregnancy remains a major public health concern in Madagascar, particularly in southern regions with unstable transmission. Intermittent preventive treatment with sulfadoxine-pyrimethamine (IPTp-SP) is a key prevention strategy, yet its coverage remains poorly documented at the district level. This study aimed to assess IPTp-SP coverage, malaria prevalence, and associated complications among pregnant women in Amboasary-Sud, southern Madagascar.
methodsA retrospective descriptive study was conducted using routine antenatal care (ANC) data from two public health facilities in 2021. A total of 1262 pregnant women attending at least one ANC visit were included. Data on sociodemographics, ANC attendance, IPTp-SP uptake, malaria rapid diagnostic test (RDT) results, and maternal-fetal outcomes were extracted and analysed. Logistic regression was used to identify factors associated with adequate IPTp-SP coverage (≥ 3 doses).
resultsAmong ANC attendees, 64.9% (819/1262) received at least one dose of IPTp-SP, but only 49.9% (409/819) completed the recommended three or more doses. Malaria RDTs were performed among symptomatic women (n = 289), with a positivity rate of 21.1% (61/289). The observed proportion of confirmed symptomatic malaria cases among all ANC attendees was 4.8% (61/1262). Maternal (n = 7) and fetal (n = 3) complications were observed exclusively among women who had not received IPTp-SP; however, the small number of events precluded causal interpretation. In multivariable analysis, living within 5 km of a health facility (aOR = 1.54, 95% CI 1.14-2.08) and attending four or more ANC visits (aOR = 2.38, 95% CI 1.76-3.21) were independently associated with adequate IPTp-SP coverage.
conclusionsIPTp-SP coverage in Amboasary-Sud remains suboptimal despite continuous drug availability. Strengthening ANC attendance and addressing geographical barriers may improve uptake of malaria prevention during pregnancy. Community-based delivery strategies could complement facility-based services in settings with limited access.
