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

backgroundSeveral studies have reported that HLA-DRB1 may be correlated with pemphigus vulgaris (PV), but most have been based on small samples and the results remain inconsistent and unclear.

objectivesTo investigate the correlation between DRB1 and PV by a meta-analysis of case-control/nonfamily studies.

methodsPubMed, Wiley Online Library, ScienceDirect, Google Scholar, Cochrane Library, Chinese National Knowledge Infrastructure and Wanfang databases were searched for studies including: (i) 'pemphigus'; and (ii) 'human leukocyte antigen', 'HLA', 'major histocompatibility complex', 'MHC' or 'DRB1'. Eighteen selected studies were used in meta-analyses to evaluate DRB1 alleles and phenotypes by calculating the respective odds ratios (ORs) and 95% confidence intervals (CIs). Stratified meta-analyses and meta-regression analysis were also conducted.

resultsThe frequencies of three genotypes (allele and phenotype, respectively) were significantly increased in PV: DRB1*04 [P-value for comparability (Pc) < 0.00001, OR 3.61, 95% CI 2.28-5.71; Pc = 0.0002, OR 4.14, 95% CI 1.98-8.65], DRB1*08 (Pc = 0.03, OR 2.25, 95% CI 1.07-4.70; Pc = 0.0003, OR 2.46, 95% CI 1.51-4.01) and DRB1*14 (Pc < 0.00001, OR 6.47, 95% CI 4.52-9.26; Pc < 0.00001, OR 9.68, 95% CI 4.47-20.98). Three others (allele and phenotype, respectively) were significantly decreased in PV: DRB1*03 (Pc < 0.00001, OR 0.28, 95% CI 0.19-0.41; Pc = 0.0001, OR 0.25, 95% CI 0.12-0.51), DRB1*07 (Pc = 0.004, OR 0.45, 95% CI 0.26-0.78; Pc = 0.0002, OR 0.27, 95% CI 0.14-0.54) and DRB1*15 (Pc = 0.001, OR 0.35, 95% CI 0.18-0.66; Pc = 0.002, OR 0.32, 95% CI 0.16-0.65). Ethnicity partially explained the heterogeneity of DRB1*07, DRB1*08 and DRB1*14 phenotypes.

conclusionsOur findings suggest that DRB1*04, DRB1*08 and DRB1*14 are statistically significant susceptibility factors for PV. Conversely, DRB1*03, DRB1*07 and DRB1*15 may be negatively associated with PV. Specific HLA-DRB1 types may influence the susceptibility or resistance to PV, which needs further investigations.
