Complement activation, placental malaria infection, and birth weight in areas characterized by unstable malaria transmission in central Sudan.
Article in Diagnostic pathology, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
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
backgroundThe pathogenesis of malaria during pregnancy is not completely understood. There are few published data on complement activation and malaria during pregnancy. This study aimed to investigate complement activation and malaria during pregnancy, and their association with hemoglobin and birth weight.
methodsA cross-sectional study was conducted at Medani, Sudan. Soluble terminal complement complex (TCC) levels were measured using ELISA in maternal and cord blood samples from 126 parturient women.
resultsThere were no Plasmodium falciparum-positive blood films from maternal peripheral blood, the placenta, or cord blood samples. Three (2.4%) and 22 (17.5%) of the placentas showed chronic and previous infection with histopathological examination, respectively, while 101 (80.2%) of them had no malaria infection. The mean [SD] of the maternal (22.4 [6.1] vs. 26.5 [3.5] ng/ml, P < 0.001) and cord blood (24.5 [4.5] vs. 26.8 [4.4] ng/ml, P = 0.024) TCC levels were significantly lower in cases of placental malaria infection (n = 25) than in those without placental malaria infection (n = 101). Linear regression showed that placental malaria infection was significantly associated with birth weight (-0.353 g, P = 0.013), but there were no associations between maternal and cord TCC levels and maternal hemoglobin, or between TCC levels and birth weight.
conclusionMaternal and cord blood TCC levels are lower in women with placental malaria infection than in those without placental malaria infection. VIRTUAL SLIDE: The virtual slide(s) for this article can be found here: http://www.diagnosticpathology.diagnomx.eu/vs/9600054761463915.
