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

objectiveGenetic factors predisposing to late-onset myasthenia gravis (LOMG) have not been clearly defined yet. However, genome-wide association studies identified Human Leukocyte Antigen (HLA) Class II alleles as a hotspot in this disease subtype. The aim of this study was to analyze the correlations of HLA Class II alleles with clinical data and titin antibodies in this patient subgroup.

methodsThis study consecutively enrolled anti-acetylcholine receptor antibody-positive, non-thymoma patients with generalized LOMG. All patients were of Italian ancestry. HLA-DRB1 and -DQB1 genotyping and serum titin antibody testing were performed in this population.

resultsA total of 107 patients (females: 28/107, 26.2%; median age of onset: 68 years, range: 50-92) were included. We found a positive association with HLA-DRB1*07 (P = 1.1 × 10

interpretationIn our study, we identified the HLA DRB1*07-DQB1*02 haplotype as a predisposing factor for the development of generalized LOMG in the Italian population.
