Intraoral appliance treatment modulates inflammatory markers and oxidative damage in elderly with sleep apnea.
Trial report in Brazilian oral research, 2024. 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
Obstructive sleep apnea (OSA) causes intermittent hypoxia, increased production of reactive oxygen species, and inflammation, which may elevate morbidity and mortality from cardiovascular disease. The objective of the present study was to investigate the effect of the intraoral appliance (IOA) as a treatment for OSA when it comes to the modulation of inflammatory markers and oxidative damage in elderly individuals. This "before and after" clinical trial included 9 patients diagnosed with OSA recruited from a multicenter randomized clinical trial study that evaluated the treatment with IOA for 60 days. Demographic and anthropometric variables, apnea and hypopnea index (AHI), and oxygen desaturation index (ODI) were collected by type III polysomnography, Epworth Sleepiness Scale, and inflammatory and oxidative damage markers (interleukin 6 (1L-6); tumor necrosis factor α (TNF-α); interleukin 10 (IL-10); thiobarbituric acid reactive substances (TBARS); total thiols; advanced oxidation protein products (AOPP), and nitric oxide (NO)). Shapiro-Wilk test, paired t-test and Pearson's correlation tests were used to analyze the results, respectively (α=0.05). The sample had a mean age of 71.86 ± 4.63 years, the majority were women (55.55%), and had a significant reduction in AHI (p=0.003), ODI (p=0.038), IL-10 (p=0.0001), AOPP (p=0.038) and TBARS levels (p=0.0001). There was a significant correlation between IL-10 and NO (r=0.855) and between TBARS and IL-6 (r=0.669), both after treatment. This study demonstrated that treating elderly patients with OSA using an IOA for 60 days reduces oxidative damage through the modulation of AOPP and TBARS.
