Psoriasis in Norway: A Prescription-based Registry Study of Incidence and Prevalence.
Article in Acta dermato-venereologica, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Epidemiological data on psoriasis in Norway are limited. The aim of this study was to provide objective national data on the incidence and prevalence of psoriasis. Patients registered in the Norwegian Prescription Database with a diagnostic code indicating psoriasis vulgaris on prescriptions were included. During the period 2004 to 2020, 272,725 patients received prescription for psoriasis vulgaris in Norway. During the period 2015 to 2020, 84,432 patients received prescription for psoriasis vulgaris for the first time. In 2020, 71,857 (97.7%) patients received topical, 7,197 (9.8%) conventional systemic and 2,886 (3.9%) biological medication for psoriasis vulgaris. In the period 2015 to 2020, the point prevalence of psoriasis was 3.8-4.6% and the incidence was 0.29-0.25%. Norway is divided into 4 geographical health regions. A latitudinal difference was observed between the 4 regions, highest in Northern Norway. In the incidence population, median age was 47-53 years and males comprised 46-50%. In this study of psoriasis vulgaris, prevalence in Norway was higher than in earlier reports from other countries. There was a small female predominance regarding incidence and prevalence; however, men had more prescriptions for systemic treatment. Prescriptions for psoriasis vulgaris showed a stable level, with a trend of increasing use of biological medication during the study period.
