Review in Current rheumatology reports, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 32 papers, 1 of them a synthesis that pooled it.

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

purpose of reviewWe review our current knowledge about the clinical features of patients with ankylosing spondylitis (AS) who possess HLA-B*27 versus those who lack this gene. RECENT

findingsERAP1 association is present only in HLA-B*27+ patients, but other genetic associations are similar between the two groups. A genetic study supports the existence of an HLA-B27-independent common link between gut inflammation and AS. It is unusual to observe familial occurrence of primary AS among families of northern European extraction that show no segregation of HLA-B*27, psoriasis, or IBD. Although there are many similarities among AS patients possessing HLA-B*27 versus those lacking this gene, the former group has a younger age of onset, a shorter delay in diagnosis, a better clinical response to tumor necrosis factor inhibitors, a greater familial occurrence, a greater risk for occurrence of acute anterior uveitis, and a lower risk for occurrence of psoriasis and IBD.
