Prevalence of Prurigo Nodularis in Poland.
Observational study in Acta dermato-venereologica, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 papers, 1 of them a synthesis that pooled 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.
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
Prurigo nodularis is a chronic skin condition that presents significant challenges for treatment and quality of life, with little known about disease prevalence. This study assessed the prevalence of prurigo nodularis in Poland using publicly maintained database case records and diagnostic codes for prurigo nodularis (L28.1) and other prurigo (L28.2). For the period 2016-18, the prevalence of prurigo nodularis increased from 5.82 to 6.52 cases per 100,000 population. The total prevalence of all prurigo diagnoses over the same period remained relatively stable, with a small increase from 9.04 to 9.26 cases per 100,000 population. Regional data largely followed the overall trend. In an analysis of 58 prurigo nodularis cases identified at the Department of Dermatology at the University of Rzeszów, 43.1% of patients were initially misdiagnosed by the referring physician. Thus, more than one-third of patients with prurigo nodularis may initially be misdiagnosed.
