The Relationship between Placental Malaria and Preeclampsia in Blantyre, Malawi.
Trial report in The American journal of tropical medicine and hygiene, 2025. 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
Preeclampsia (PreE) and placental malaria (PM) are leading causes of perinatal morbidity and mortality in Africa with overlapping pathophysiology. Utilizing data collected during a randomized, controlled clinical trial of intermittent preventive therapy during pregnancy in Malawi, we examined the association between PM and PreE, including severe manifestations, such as eclampsia. All singleton pregnancies with placental histopathology and polymerase chain reaction (PCR) were included. Among 751 pregnancies, 125 (16.7%) had evidence of PM by histopathology or PCR identifying PM parasites, including 105 with hemozoin pigment indicative of infection during early pregnancy. Twenty-five patients (3.3%) had PreE without eclampsia, 6 (0.7%) had eclampsia, and 98 (13.0%) had any hypertensive disorder. Individuals with hemozoin had nearly twice the rate of PreE as those without, although this difference did not achieve statistical significance (6.7% versus 3.7%, P = 0.16). This study is limited by sample size and was underpowered to detect this difference. Further research characterizing the relationship between PM and PreE is warranted.
