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

purposeBehçet's disease (BD) is known to be associated with HLA-B*51 in many different ethnic groups. Recently, the major histocompatibility complex class I chain-related gene A (MICA), located near the HLA-B gene, has been proposed as a candidate gene for BD susceptibility in several ethnic groups. To compare the relative contribution of MICA polymorphisms and HLA-B*51 to BD in different ethnic groups, we studied MICA polymorphisms in Turkish BD patients.

methodsThirty-three Turkish BD patients and 65 healthy controls were enrolled for analysis of polymorphisms in the extracellular domains of MICA.

resultsThe phenotype frequencies of MICA*009 were significantly higher in BD patients (75.8%) than in controls (29.2%) (P = 0.000015). HLA-B*51 was also significantly more frequent in BD patients (81.8%) than in controls (29.2%) (P = 0.0000007). A strong association existed between MICA*009 and HLA-B*51. To assess the confounding effect of MICA*009 on HLA-B*51, we performed a stratification analysis that showed that BD was distinctly associated only with HLA-B*51.

conclusionOur results indicate that the major susceptibility gene for BD is HLA-B*51 and that the association between MICA*009 and BD arises from a strong linkage disequilibrium with HLA-B*51. However, we suggest that MICA*009 likely elicits an immune effect secondary to BD.
