1 · What the graph read from 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.

2 · The registry

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

The aim of this study was to determine whether the protein tyrosine phosphatase nonreceptor 22 (PTPN22) C1858T polymorphism confers susceptibility to rheumatoid arthritis (RA) in populations with different ethnicities. A meta-analysis was conducted on the PTPN22 C1858T polymorphism involving eighteen studies, which in total contained 20344 RA patients and 21828 controls. Meta-analysis revealed an association between the PTPN22 C1858T polymorphism T allele and RA in all subjects (odds ratio [OR] = 1.637, 95% confidence interval [CI] = 1.514-1.770, P < 0.001). After stratification by ethnicity, analysis indicated that the PTPN22 C1858T polymorphism T allele was significantly associated with RA in Europeans and Non-Europeans (OR = 1.587, 95% CI = 1.486-1.696, P < 0.001; OR = 1.748, 95% CI = 1.274-2.398, P < 0.001). Meta-analysis of the CT + TT genotype showed the same result patterns as that shown by the PTPN22 C1858T polymorphism T allele. Furthermore, a direct comparison between rheumatoid factor (RF)-positive and -negative subjects revealed a significant association with the T allele in RA patients with RF, but not in subjects without RF. In conclusion, this meta-analysis confirms that the PTPN22 C1858T polymorphism is associated with RA susceptibility in different ethnic groups, especially in Europeans, and the PTPN22 C1858T polymorphism T allele is significantly more prevalent in RF-positive patents than in RF-negative patients.
