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

backgroundMastocytosis is a disease characterized by accumulation of aberrant mast cells and mediator-related symptoms and is divided into systemic mastocytosis (SM) and cutaneous mastocytosis (CM). The epidemiology of mastocytosis remains incompletely understood.

objectiveTo estimate the incidence, prevalence, overall survival (OS) and burden of comorbidities in adult mastocytosis patients identified in Swedish population-based registries.

methodsIndividuals (≥ 20 years of age) with a mastocytosis diagnosis in the National Patient Register (NPR) and/or the Swedish Cancer Register (SCR) between 2001 and 2018, were identified. In a matched cohort design, for each case five randomly selected mastocytosis-free comparators matched on age, sex, and county of residence were chosen from the Population Register. The Kaplan-Meier method was used to compare OS between individuals with mastocytosis and comparators. Information on concomitant disease at baseline was assessed by use of the Charlson Comorbidity Index (CCI).

resultsWe identified 2,040 adults with a mastocytosis diagnosis yielding an annual incidence of 1.56 per 100,000 (95% CI 1.29-1.87) and a prevalence of 23.9 per 100,000 (95% CI 22.8-25.0). The comorbidity burden was higher, and the OS lower, in patients with mastocytosis compared to comparators.

interpretationWe found a higher incidence and prevalence of mastocytosis compared to assessments in other settings and confirmed that the prognosis generally is favorable. Of special note was evidence of a higher comorbidity burden in mastocytosis patients compared to the background population. LIMITATIONS: Underreporting and inconsistencies in the use of diagnostic codes.
