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

Prurigo nodularis is an itchy skin disease with unknown epidemiology. This study aimed to describe the epidemiology of prurigo nodularis compared with that of psoriasis. The German sickness fund claims database, with 2,783,175 continuously insured patients, included 1,720 patients diagnosed with prurigo nodularis and 51,390 with psoriasis. Patients with prurigo nodularis were averagely 8 years older than psoriasis patients and more often were women (p < 0.001). Annual incidence was a constant 0.02% in prurigo nodularis, and decreased steadily from 0.53 to 0.42% in psoriasis; cumulative incidence was 0.1% for prurigo nodularis and 1.9% for psoriasis. Prevalence was 0.1% for prurigo nodularis and 4.7% for psoriasis, with a 1-year mortality of 5.4% for prurigo nodularis and 1.2% for psoriasis (p < 0.001). The most frequent pre-existing comorbidities in patients with prurigo nodularis were inflammatory dermatoses and depression. This epidemiological study found a low prevalence of prurigo nodularis, manifesting different demographics and comorbidities compared with psoriasis.
