A comparative study on proinflammatory cytokines interleukin-17A and interleukin-17F expressions in whole blood of patients with COVID-19.
Article in Iranian journal of microbiology, 2025. 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 and Objectives: Coronavirus disease 2019 (COVID-19), due to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has expanded rapidly to all over the world. Interleukin-17 is one of the inflammatory cytokines which is highly expressed in the blood of individuals with COVID-19. Our aim in the present survey was to assess the mRNA expression levels of cytokine IL-17A, IL-17F and TNF-α in the blood of COVID-19 patients compared with healthy control individuals. Materials and Methods: A total of 69 patients including 32 mild patients, 20 severe and 17 asymptomatic patients in comparison with 25 healthy controls were evaluated. To measure the expression profile of IL-17A and IL-17F in whole blood, quantitative PCR was used. Results: Asymptomatic, mild, and severe SARS-CoV-2 infections were found to have significantly higher levels of IL-17A and IL-17F mRNAs than the healthy group (fold change IL-17A: 3.778; p= 0.002, 4.003; p= 0.001, 2.608; p= 0.0001 respectively, fold change IL-17F: 2.967; p= 0.003, 3.819; p= 0.001, 2.617; p= 0.0012 respectively). TNF-α mRNA expression was also measured, which shows an approximately similar increase compared to IL-17 (fold change: 2.726; p= 0.002, 2.383; P= 0.001, 2.631; p= 0.001, respectively). Conclusion: SARS-CoV-2 infection severity was associated with blood levels of IL-17A and IL-17F mRNA.
