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

objectivesThe incidence and prevalence of allergies worldwide has been increasing and allergy services globally are unable to keep up with this increase in demand. This systematic review aims to understand the delivery of allergy services worldwide, challenges faced and future directions for service delivery.

methodsA systematic scoping review of Ovid, EMBASE, HMIC, CINAHL, Cochrane, DARE, NHS EED and INAHTA databases was carried out using predefined inclusion and exclusion criteria. Data on the geographical region, study design and treatment pathways described were collected, and the findings were narratively reported. This review followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines.

results205 publications were screened and 27 selected for review. Only 3 were prospective studies, and none included a control group. There were no eligible publications identified from North America, Africa, Australia and most parts of Asia. Most publications relate to allergy services in the UK. In general, allergy services globally appear not to have kept pace with increasing demand. The review suggests that primary care practitioners are not being adequately trained in allergy and that there is a paucity of appropriately trained specialists, especially in paediatric allergy. There appear to be considerable barriers to service improvement, including lack of political will and reluctance to allocate funds from local budgets.

conclusionsDemand for allergy services appears to have significantly outpaced supply. Primary and secondary care pathways in allergy seem inadequate leading to poor referral practices, delays in patient management and consequently poor outcomes. Improvement of services requires strong public and political engagement. There is a need for well-planned, prospective studies in this area and a few are currently underway. There is no evidence to suggest that any given pathway of service provision is better than another although data from a few long-term, prospective studies look very promising.
