Polymorphisms in Maternal Selected Folate Metabolism-Related Genes in Neural Tube Defect-Affected Pregnancy.
Article in Advanced biomedical research, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Background: Neural tube defects (NTDs) are abnormalities of the brain and spinal cord, which occur as a result of failure in neural tube closure during embryogenesis. Causes of NTDs are complex and multiple, with hereditary, lifestyle, and environmental factors appearing to play a role. In spite of their impact on public health, the role genetics play on NTDs in Ethiopia is lacking. In this study, the role of polymorphisms in MTHFR 677C > T (rs1801133), MTHFR 1298A > C (rs1801131), MTRR 66A > G (rs1801394), RFC1 80A > G (rs1051266), and TCN2 776C > G (rs1801198) on the risk of having NTD-affected pregnancy was investigated. Materials and Methods: One hundred women with NTD-affected pregnancy and 100 women with normal pregnancy were included in the study. DNA was extracted from saliva and genotyping for five polymorphisms in four genes was analyzed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). The departure of the genotype's distribution from Hardy-Weinberg equilibrium (HWE) was evaluated using the x Results: The statistically significant difference was absent in the genotype and allele frequencies for all the analyzed polymorphisms between cases and controls ( Conclusion: MTHFR 677C > T, MTHFR 1298A > C, MTRR 66A > G, RFC1 80A > G, and TCN2 776C > G polymorphisms lack association with the risk of having a pregnancy affected by NTD. The role of other genes or environmental factors in NTD etiology needs to be investigated.
