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 impact of sulfadoxine-pyrimethamine (SP) used as intermittent preventive treatment during pregnancy (IPTp-SP) on mutant parasite selection has been poorly documented in Burkina Faso. This study sought first to explore the relationship between IPTp-SP and the presence of mutant parasites. Second, to assess the relationship between the mutant parasites and adverse pregnancy outcomes.
methodsFrom September to December 2010, dried blood spots (DBS) were collected during antenatal care visits and at delivery from 109 pregnant women with microscopically confirmed falciparum malaria infection. DBS were analysed by PCR-restriction fragment length polymorphism (PCR-RFLP) for the polymorphisms at codons 51, 59, 108, and 164 of the Pfdhfr gene and codons 437 and 540 in the Pfdhps gene.
resultsBoth the Pfdhfr and Pfdhps genes were successfully genotyped in 92.7% (101/109) of the samples. The prevalence of Pfdhfr mutations N51I, C59R and S108N was 71.3, 42.6 and 64.4%, respectively. Overall, 80.2% (81/101) of samples carried the Pfdhps A437G mutation. None of the samples had the Pfdhfr I164L and the Pfdhps K540E mutations. The prevalence of the triple mutation N51I + C59R + S108N was 25.7% (26/101). The use of IPTp-SP was associated with a threefold increased odds of Pfdhfr C59R mutation [crude OR 3.29; 95% CI (1.44-7.50)]. Pregnant women with recent uptake of IPTp-SP were at higher odds of both the Pfdhfr C59R mutation [adjusted OR 4.26; 95% CI (1.64-11.07)] and the Pfdhfr intermediate-to-high resistance, i.e., ≥ 2 Pfdhfr mutations [adjusted OR 3.45; 95% CI (1.18-10.07)]. There was no statistically significant association between the presence of the Pfdhfr intermediate-to-high resistance and parasite densities or both maternal haemoglobin level and anaemia.
conclusionThe data indicate that despite the possibility that IPTp-SP contributes to the selection of resistant parasites, it did not potentiate pregnancy-associated malaria morbidity, suggesting the continuation of SP use as IPTp in Burkina Faso.
