Infodemiology and hearing: analysis of the search behavior of the Brazilian population.
Article in CoDAS, 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
purposeTo investigate the online search behavior of the Brazilian population for information related to hearing loss, tinnitus, and dizziness.
methodsThis ecological and infodemiological study analyzed online search behavior in Brazil for the terms "Hearing Loss," "Dizziness," and "Tinnitus" from January 2014 to May 2024, using data from Google Trends™. Normalized relative search volumes (VPR) were calculated, and correlations between the terms were analyzed using Spearman's test, trend analysis with the Mann-Kendall test, and structural breaks with a significance level of 5%.
resultsSignificant correlations were found between the terms "Dizziness" and "Hearing Loss," "Tinnitus" and "Hearing Loss," and "Tinnitus" and "Dizziness." An increasing trend in VPR was observed for "Hearing Loss," "Dizziness," and "Tinnitus." Structural breaks for each search term occurred in the following periods: Hearing Loss (two breaks): February 2016 and January 2021; Dizziness (five breaks): July 2015, July 2017, February 2019, April 2020, and December 2021; and Tinnitus (five breaks): April 2015, April 2017, March 2018, April 2020, and April 2022.
conclusionThe search behavior over the past decade reveals a growing interest in information about hearing loss, tinnitus, and dizziness, with correlated results among the three terms. Sergipe had the highest search volume for "hearing loss," Maranhão for "dizziness," and São Paulo for "tinnitus."
