The impact of ex vivo ozone injection into the synovial fluid in patients with knee osteoarthritis: A controlled clinical trial.

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
Objectives: This study aimed to examine the effect of varying ozone doses on proinflammatory cytokine levels in the synovial fluid collected from individuals with knee osteoarthritis. Patients and methods: The controlled clinical trial was conducted with 82 patients (61 females, 21 males; mean age: 63.1±10.0 years; range, 40 to 73 years) between 21 April 2023 and 20 May 2023. Synovial fluid samples were collected from the patients under ultrasound guidance and divided into three tubes, one of which was not injected with ozone, and the other two were injected with 10 and 30 gamma (γ) ozone, respectively. The total antioxidant status, total oxidant status, oxidative stress index, interleukin (IL)-1 beta (β), IL-6, and tumor necrosis factor-alpha (TNF-α) in the joint fluids were measured. Results: The oxidative stress index and IL-1 β, IL-6, and TNF-α levels in the synovial fluid were lower at 10 and 30 γ compared to 0 and 10 γ, respectively. Conclusion: This study showed that
