Serum levels of IL-4, IL-13 and IL-33 in patients with age-related macular degeneration and myeloproliferative neoplasms.
Article in Scientific reports, 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
Immune responses play a key role in the pathogenesis and progression of myeloproliferative neoplasms (MPN) and age-related macular degeneration (AMD). Recent studies suggested using MPNs as a "Human Inflammation Model" of drusen development and previous results showed interleukin-4 (IL-4) dysregulation in MPN and AMD. IL-4, IL-13 and IL-33 are all cytokines involved in the type 2 inflammatory response. This study investigated the cytokine levels of IL-4, IL-13 and IL-33 in serum of MPN and AMD patients. This cross-sectional study included 35 patients with MPN with drusen (MPNd) and 27 with MPN and normal retinas (MPNn), 28 patients with intermediate AMD (iAMD) and 29 with neovascular AMD (nAMD). With immunoassays, we quantified and compared levels of IL-4, IL-13 and IL-33 in serum between the groups. The study was conducted at Zealand University Hospital, Roskilde, Denmark, between July 2018 and November 2020. The serum levels of IL-4 were significantly higher in the MPNd group than in the MPNn group (p = 0.003). In regard to IL-33, the difference between MPNd and MPNn was not significant (p = 0.069), however, when subdivided into subgroups, a significant difference was found between polycythemia vera patients with drusen and those without drusen (p = 0.005). We found no IL-13 difference between the MPNd and MPNn groups. Our data didn't show any significant IL-4 or IL-13 serum level difference between the MPNd and iAMD groups but in regard to IL-33, data recorded a significant serum level difference between the two groups. There was no statistically significant difference between the MPNn, iAMD and nAMD groups in levels of IL-4, IL-13 and IL-33. These findings suggested that the serum levels of IL-4 and IL-33 might play a role in drusen development in MPN patients. The results might represent the type 2 inflammatory arm of the disease. The findings support the association between chronic inflammation and drusen.
