Carriage of Mutant Dihydrofolate Reductase and Dihydropteroate Synthase Genes among Plasmodium falciparum Isolates Recovered from Pregnant Women with Asymptomatic Infection in Lagos, Nigeria.
Article in Medical principles and practice : international journal of the Kuwait University, Health Science Centre, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 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
objectiveTo assess N51I, C59R and S108N polymorphisms of dihydrofolate reductase (dhfr) and A437G and K540E of dihydropteroate synthase (dhps) genes of P. falciparum isolates recovered from pregnant women with asymptomatic malaria in a coastal setting in Nigeria. SUBJECTS AND
methodsA total of 107 consenting and consecutively enrolled pregnant women (mean age ± standard deviation, 26.6 ± 4.5 years) attending antenatal care at the Iru/Victoria Island Primary Health Centre, Lagos, were screened for peripheral malaria by microscopy, by a histidine-rich protein-2-based rapid diagnostic test (RDT) and by polymerase chain reaction (PCR) using finger-pricked and dot blood samples. DNA was extracted from the blood and used for dhfr and dhps gene polymorphism analyses by PCR and restriction fragment length polymorphism. The sociodemographic and parasite data obtained were analysed.
resultsOf the 107 patients, 34 (31.8%), 46 (43%) and 40 (37.4%) were found to be P. falciparum infected using microscopy, RDT and corrected RDT-PCR, respectively (p < 0.05). The prevalence of P. falciparum isolates with mutant and mixed genotypes of dhfr at codons 51, 59 and 108 was 70, 75 and 80%, respectively, and the triple mutation in the homozygous form was 35%. The prevalence of the homozygous quintuple dhfr plus dhps mutant was 5%, while that of the P. falciparum isolates with mutant or mixed genotypes of dhps at codons 437 and 540 was 37.5 and 22.5%, respectively.
conclusionThis study revealed the emergence of the K540E mutation among the parasite population in Lagos. However, it supports the implementation of the intermittent preventive treatment of malaria during pregnancy with sulphadoxine-pyrimethamine with continuous effectiveness monitoring in the study area.
