Association of TBX20 gene polymorphism with congenital heart disease in Han Chinese neonates.
Article in Pediatric cardiology, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
As a transcription factor mainly expressed in cardiovascular system, T-box 20 (TBX20) plays an important role in embryonic cardiovascular system development and adult heart function. Previous studies have identified associations of two SNPs in the T-box DNA-binding domain of TBX20 with congenital heart disease (CHD) in two Caucasian families, but the associations of TBX20 mutations underlying the more common populations with CHD remain to be uncovered. In this study, 25 unrelated Chinese Han neonates with CHD and 25 healthy children as controls were investigated for TBX20 mutations. SNP genotyping was performed by PCR-DNA sequencing. The selected SNPs were well genotyped and SNP rs3999941 was found to be strongly associated with CHD (p = 0.007). The minor allele of rs3999941 showed a high-risk factor for CHD (OR 4.24; 95 % CI 1.41-12.71). Besides, we found a new SNP site located at the 657th nucleotide of the exon 5 of TBX20 gene which may also be associated with CHD, c.657A>C. The frequency was significantly different between two groups (p = 0.011), the minor allele of SNP c.657A>C also showed a risk factor for CHD (OR 2.56; 95 % CI 1.02-6.46). These findings suggested that the TC genotype of SNP rs3999941 and AC genotype of the new SNP c.657A>C in the TBX20 gene may be risk factors for CHD and thus screening of these SNPs may have some implications in the prevention and treatment of CHD in Han Chinese children.
