Nailfold Capillaroscopy Findings in Patients With Psoriasis Vulgaris and Different Domains of Psoriatic Arthritis.
Article in Journal of psoriasis and psoriatic arthritis, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Psoriasis is a chronic autoimmune disease with longtime activity and multisystem affection. Nailfold capillaroscopy (NC) is a simple noninvasive microscopic tool useful for identification of nailfold microvasculopathy. Objective: The present study aimed to compare NC findings in patients with psoriasis vulgaris (PsV) and psoriatic arthritis (PsA) with different clinical domains. Methods: The present cross-sectional study included 200 psoriasis patients classified into five 40-patient groups: group I (GI) included PsA patients with predominant peripheral arthritis; group II (GII) included PsA patients with predominant peripheral arthritis and dactylitis and/or enthesitis; group III (GIII) included PsA patients with predominant axial affection; group IV (GIV) patients included PsA patients with predominant axial affection and dactylitis and/or enthesitis and group V (GV) included patients with PsV. In addition, there were 40 age and sex-matched healthy controls (GVI). Results: The studied patients had capillary density of 6.7 ± 3.5/mm with 90 patients (45.0 %) having reduced capillary density. GI-GIV patients had significantly lower capillary density and higher frequency of patients with reduced capillary density as compared to GV patients. The reported capillary dimension in the studied patients is 15.7 ± 7.9 μm and 55 patients (27.5 %) had large/giant capillaries. Patients in GV had significantly lower capillary dimension in comparison to GI-GIV patients. There were 64 patients (32.0 %) with abnormal capillary morphology and 47 patients (23.5 %) with capillary hemorrhages. Conclusions: PsA patients of all domains have lower capillary density and larger capillary dimensions as compared to PsV patients.
