Trial report in The Journal of infectious diseases, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02793622 (Prevention of Malaria in HIV-uninfected Pregnant Women and Infants), which is not on this map. Cited by 22 papers, 1 of them a synthesis that pooled it.

1 · What the graph read from it

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.

Abstract

backgroundPlacental malaria is a major cause of adverse birth outcomes. However, data are limited on the relationships between longitudinal measures of parasitemia during pregnancy and placental malaria.

methodsData came from 637 women enrolled in a randomized controlled trial of intermittent preventive treatment of malaria in pregnancy (IPTp) from Uganda. Plasmodium falciparum parasitemia was assessed using microscopy and ultrasensitive quantitative PCR at intervals of 28 days from 12 to 20 weeks gestation through delivery. Multivariate analysis was used to measure associations between characteristics of parasitemia during pregnancy and the risk of placental malaria based on histopathology.

resultsOverall risk of placental malaria was 44.6%. None of the 34 women without parasitemia detected during pregnancy had evidence of placental malaria. Increasing proportion of interval assessments with parasitemia and higher parasite densities were independently associated with an increased risk of placental malaria. Higher gravidity and more effective IPTp were associated with a decreased risk of placental malaria. Women with parasitemia only detected before the third trimester still had an increased risk of placental malaria.

conclusionsThe frequency, density, and timing of parasitemia are all important risk factors for placental malaria. Interventions should target the prevention of all levels of parasitemia throughout pregnancy.
