Supplementation with açaí (Euterpe Oleracea Martius) for the treatment of chronic tinnitus: effects on perception, anxiety levels and oxidative metabolism biomarkers.
Trial report in CoDAS, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
purposeTo investigate the effects of antioxidant supplementation with açaí extract on the discomfort with chronic tinnitus and the relationship with the levels of anxiety and oxidative metabolism, not excluding the overlap of diseases.
methodsRandomized, placebo-controlled clinical trial. 30 individuals participated, with an average of 50.5 years, 14 males and 16 females, with normal hearing thresholds or sensorineural hearing loss up to mild degree, divided into two groups: Placebo Group (without active) and, Açaí Group (100mg of açaí extract). The following procedures were applied before and after three months of treatments: Tinnitus Handicap Inventory (THI), Beck's Anxiety Inventory (BAI) and blood samples for evaluation of oxidative stress biomarkers (Lipid Peroxidation and Protein Carbonylation).
resultsThere was a reduction in the discomfort of tinnitus for the açaí group verified through THI (p = 0.006). Significant differences were found in the score of common symptoms for anxiety disorders in the placebo group (p = 0.016), however, the same was not observed for oxidative metabolism biomarkers, although there was a decrease in post-treatment values for all groups.
conclusionOral antioxidant supplementation, with açaí extract, showed favorable effects on tinnitus, reducing discomfort with the symptom, regardless of the underlying etiology, and can be considered a treatment modality. However, the effect of this supplementation on anxiety symptoms and oxidative stress biomarkers needs further investigation.
