Platelet-Rich Plasma for Rhinitis Medicamentosa: A Promising Histopathological Study in an Animal Model.
Article in Otolaryngology--head and neck surgery : official journal of American Academy of Otolaryngology-Head and Neck Surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectiveTo investigate whether platelet-rich plasma (PRP) has an efficacy on histopathologic changes in rhinitis medicamentosa (RM) in a rat model. STUDY
designExperimental animal study.
settingUniversity animal laboratory.
methodsForty Wistar albino rats were randomly assigned to five groups to assess the effects of various treatments on RM. Group 1 received intranasal normal saline solution (NSS) for 60 days and served as the negative control. Group 2 was administered intranasal oxymetazoline for 60 consecutive days to induce RM. After decapitation, histopathological evaluation confirmed the development of RM in group 2. The remaining three groups were then similarly treated with oxymetazoline for 60 days. Following this period, group-specific treatments were applied for an additional 15 days: group 3 received NSS, group 4 was treated with intranasal corticosteroids, and group 5 received intranasal PRP. Nasal mucosal samples were harvested and subjected to histopathological evaluation to determine treatment-related changes.
resultsIntranasal PRP treatment significantly reduced submucosal edema and improved submucosal gland degeneration (SGD) scores in the nasal mucosa. Moreover, PRP treatment led to a greater reduction in total histopathological score compared to steroid treatment (P = .007).
conclusionThis study demonstrated that PRP administration effectively ameliorates submucosal edema, SGD, and total histopathologic score in experimentally induced RM. Given that PRP is an autologous product with a low risk of side effects, it may serve as a promising alternative to steroids in the treatment of RM.
