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

introductionChronic spontaneous (previously known as idiopathic) urticaria (CSU) is a chronic skin disease with the potential for natural remission. The objectives of this targeted literature review were to identify evidence on the clinical course of CSU, including remission rates, and to estimate cumulative remission rates for different time points.

methodsElectronic databases (MEDLINE, MEDLINE-In Process, Embase, Web of Science, BIOSIS Previews and the Cochrane Library) and relevant conference proceedings were searched to identify studies involving patients with CSU aged ≥ 12 years that provide data on remission rates and disease duration. Observational studies with patient follow-ups of ≥ 1 year or review articles were included. Data extracted from five selected studies were used to run Kaplan-Meier (KM) analyses and best-fit distributions to calculate remission rates per 4-week period and weighted averages.

resultsTen publications were included in this review. The proportion of patients achieving remission within year 1 ranged from 21 to 47%, while reported remission rate estimates at year 5 were 34% and 45%. Based on calculated 4-weekly remission rates, cumulative remission estimates ranged from 9 to 38% at year 1, from 29 to 71% at year 5 and from 52 to 93% at year 20. Cumulative weighted average estimates for the proportion of patients remitting at years 1, 5 and 20 were 17%, 45% and 73%, respectively.

conclusionsPublished evidence suggests that CSU is a self-limiting condition with variable disease severity and duration, apparently dependent on multiple factors. However, data sources differed in terms of definitions of disease severity and remission, as well as in conclusions on influencing factors. Further studies and uniform definitions are required.
