Incidence of Psoriatic Arthritis in Patients with Skin Psoriasis and Associated Risk Factors: A Retrospective Population-based Cohort Study in Swedish Routine Clinical Care.
Article 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 16 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
The incidence of psoriatic arthritis in patients with psoriasis is unclear; existing estimates differ by a factor of ten. Complete population-level data is needed to provide accurate estimates with high confidence. A total of 123,814 adults with psoriasis, free from pre-existing psoriatic arthritis, were identified in population-based data from secondary care in Sweden during 2007 to 2017. Incidence was calculated as the number of psoriatic arthritis diagnosis events per 100 patient-years. Time to diagnosis was assessed using cumulative incidence and Cox proportional hazards models to identify risk factors. Incidence of psoriatic arthritis in patients with psoriasis was 1.69 per 100 patient-years (95% confidence interval 1.65-1.72) overall, and 1.48, 3.00, and 5.49 per 100 patient-years in patients with mild, moderate and severe psoriasis, respectively. Risk of psoriatic arthritis was 3.2 times higher amongst patients with severe psoriasis compared with mild disease. Dermatologists should regularly assess risk factors for psoriatic arthritis in clinical practice in order to improve the detection of psoriatic arthritis.
