High-resolution HLA analysis of primary and secondary Sjögren's syndrome: a common immunogenetic background in Mexican patients.
Article in Rheumatology international, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
To compare the distribution of HLA-A, B, DRB1 and DQB1 alleles among Mexican patients with primary Sjögren Syndrome (pSS), secondary SS (sSS), connective tissue disease (CTD) without (w/o) SS and historical ethnically healthy controls. We included 28 pSS, 30 sSS, 96 CTD w/o SS patients and 234 controls. HLA-A, B, DRB1 and DQB1 were amplified and sequenced using the Allele SEQR Sequenced Based Typing Kits and analyzed on the ABI Prism*3130 DNA Analyzer using the Assign software. Gene frequencies were obtained by direct counting. Contingence tables of 2 × 2 were generated and analyzed by the Mantel-Haenzel χ (2) or Fisher's test (EPIINFO program). We reported odds ratios (OR) and corrected p values. SS patients showed increased frequencies of A*68:01 and DRB1*14:06 alleles when compared to CTD w/o SS (OR 4.43, 95 % CI 1.35-14.14, p = 0.007 and OR 14, 95 % CI 1.68-116, p = 0.001, respectively) and a higher prevalence of DRB1*01:01 (OR 5.9, 95 % CI 2.13-16.56, p = 0.003) and HLA-B*35:01 (OR 3.70, 95 % CI 1.92-7.12, p = 0.004) when compared with controls. pSS patients had a higher frequency of DRB1*14:06 allele than sSS (OR 16, 95 % CI 1.59-390, p = 0.001). Anti-Ro/SSA positivity was associated with B*51:01 (OR 10.11, 95 % CI 1.09-245, p = 0.02) and DRB1*03:01 alleles (OR 4.26, 95 % CI 1.01-18.89, p = 0.029), whereas the A*01:01 allele was associated with anti-La/SSB positivity (OR 4.75, 95 % CI 1.32-16.92, p = 0.003). In our population, the DRB1*14:06 allele was associated with primary and secondary SS implying that both varieties bear a similar immunogenetic background.
