Aurora kinase genetic polymorphisms: an association study in Down syndrome and spontaneous abortion.
Article in Human cell, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Aneuploidies, such as Down syndrome (DS), are the leading cause of pregnancy loss. Abnormalities in aurora kinase proteins result in genomic instability and aneuploidy, mainly in tumors. Thus, polymorphisms in Aurora kinase genes could influence the occurrence of DS and spontaneous abortion. A case-control study was conducted including 124 mothers of DS children (DSM) and 219 control mothers (CM) to investigate DS risk according to AURKA and AURKC polymorphisms. Genotyping was performed using TaqMan real-time PCR. The minor allele frequency (MAF) observed in AURKA rs2273535 was, respectively, 0.23 in DSM and 0.20 in CM, whereas the frequency of the AURKC rs758099 T allele was 0.32 in case and 0.33 in control mothers. Statistical analysis showed no significant difference in the distribution of genotypes and allele frequencies between DSM and CM. According to previous history of spontaneous abortion, the AURKA rs2273535 genotypes (TT + AT vs. AA: OR 2.54, 95% CI 1.13-5.71, p = 0.02; AT vs. AA: OR 2.39, 95% CI 1.03-5.51, p = 0.04; T vs. A: OR 2.08, 95% CI 1.12-3.90, p = 0.02) and AURKC rs758099 (TT vs. CC: OR 4.34, 95% CI 1.03-18.02, p = 0.04; TT + CT vs. CC: OR 2.52, 95% CI 1.02-6.23, p = 0.04; T vs. C: OR 2.03, 95% CI 1.09-3.80, p = 0.02) were observed as risk factors for spontaneous abortion in case mothers. Our study suggests a possible relationship between AURKA/AURKC variants and increased risk of spontaneous abortion within Down syndrome mothers.
