Evaluation of filaggrin 2 expression in dogs with atopic dermatitis before and after oclacitinib maleate administration.
Article in Veterinary dermatology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundCanine atopic dermatitis (cAD) is a chronic, inflammatory, multifactorial and pruritic disease. The presence of skin barrier impairment (e.g. filaggrin alterations), along with abnormal immune responses, can negatively impact cutaneous barrier function.
objectivesTo evaluate the filaggrin 2 (FLG2) expression in atopic dogs before and after the administration of oclacitinib maleate. ANIMALS: Sixteen privately owned dogs with a diagnosis of cAD and 10 healthy control dogs. MATERIALS AND
methodsOclacitinib maleate monotherapy at 0.5 mg/kg, orally, twice-daily for the first 14 days and once-daily for 16 additional days, was administered to the atopic dogs. Skin biopsies from lesional and nonlesional skin were obtained from atopic dogs on Day(D)0 and D30 and from the same anatomical locations from the control group on D0. Immunohistochemical investigation was performed using a primary custom-made anti-canine-filaggrin 2 polyclonal antibody. Immunolabelled slides were scanned and FLG2 expression was measured. Data were analysed and a p-value ≤0.05 was considered statistically significant.
resultsThere was a higher FLG2 expression in control skin when compared with atopic skin (lesional and nonlesional) on D0 (p = 0.033). FLG2 expression comparison between control and D30 (nonlesional) did not show a significant difference (p = 0.509). A significant increase in FLG2 expression in atopic nonlesional skin on D30 compared with nonlesional skin on D0 was also observed (p = 0.014). CONCLUSIONS AND CLINICAL RELEVANCE: Oclacitinib maleate could have a positive impact on cutaneous barrier structure, improving FLG2 expression by decreasing inflammation and cutaneous trauma.
