Lack of associations between two previously identified susceptible single nucleotide polymorphisms of interleukin-23 receptor gene and ankylosing spondylitis: a replication study in a Chinese Han population.
Article in BMC musculoskeletal disorders, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundThe human leukocyte antigen (HLA)-B27 gene is considered to be a major gene associated with predisposition to ankylosing spondylitis (AS); however, studies have demonstrated that non-HLA-B27 genes also contribute substantially to the susceptibility to AS. Two single nucleotide polymorphisms (SNPs), rs1004819 and rs10889677, of the interleukin-23 receptor (IL-23R) gene have been shown to be associated with AS susceptibility in European populations. However, ethnicity factors contribute to population splitting and genetic variation, and ethnic-specific genetic association studies are needed to validate these associations in patients from different ethnic backgrounds. This study therefore aimed to replicate the associations between these two SNPs and AS susceptibility in a Chinese Han population.
methodsA total of 195 AS patients and 203 normal controls were recruited in this study. Two IL-23R gene SNPs, rs1004819 and rs10889677 were selected. Genotyping was performed in all subjects using the TaqMan probe method. Genotype and allele frequencies were compared between AS patients and normal controls by χ2 tests.
resultsThere were no significant differences in either the genotype frequencies (TT 36.4%, TC 48.7% and CC 14.9% in AS patients; TT 35.0%, TC 50.0% and CC 15.0% in normal controls) or allele frequencies (T 60.8% and C 39.2% in AS patients; T 60.0% and C 40.0% in normal controls) of rs1004819 between AS patients and normal controls (P > 0.05). In addition, both the genotype frequencies (AA 51.3%, AC 43.1% and CC 5.6% in AS patients; AA 57.6%, AC 35.5% and CC 6.9% in normal controls) and allele frequencies (A 72.8% and C 27.2% in AS patients; A 75.4% and C 24.6% in normal controls) of rs10889677 were also comparable between AS patients and normal controls (P > 0.05).
conclusionsThis study found no evidence for an association between either of the two previously identified AS-susceptibility IL-23R SNPs (rs1004819 and rs10889677) and onset of AS, indicating a possible difference in pathogenesis of AS between Chinese and European patients.
