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

Background: The α-gal syndrome is a food allergy to galactose-α-1,3-galactose present in mammalian meat; it usually develops after tick bites. Despite being considered an emerging health problem, little is known about the geographic risk factors and patterns of α-gal sensitization. Objective: The aim of this study was to assess geographic clusters of α-gal sensitization and determine whether distance from home address to the forest and tick abundance are risk factors for α-gal sensitization in a Danish adult population. Methods: We utilized 3 population-based health examination studies that were conducted in 2011-2017 and covered a total of 8742 participants living in a suburban area. All participants were screened for a level of serum-specific IgE to α-gal of 0.1 kU Results: There were 344 cases of galactose-α-1,3-galactose-specific IgE level being 0.1 kU Conclusion: In a general, individuals residing in a suburban area had 9% higher odds of being sensitized to α-gal the closer they lived to a forest, thus supporting exposure to ticks as a risk factor for sensitization to α-gal.
