Seasonality of bruxism: evidence from Google Trends.
Observational study in Sleep & breathing = Schlaf & Atmung, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 papers, 1 of them a synthesis that pooled it.
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
objectiveSeasonality of bruxism and its symptoms has not been tested and reflects a major niche in our understanding and the epidemiology of bruxism. Our aim is to use the Google Trends data to examine whether there was a seasonal pattern in the Google search volumes of bruxism and its symptoms on a population basis.
methodsIn the observational, ecological research, we interrogated Google Trends for the following query terms: [bruxism] and [teeth grinding + teeth clenching] to obtain the internet search query volume. These queries were searched within the USA, the UK, Canada, and Australia from January 2004 to December 2017.
resultsThe cosinor analysis showed statistically significant seasonal patterns in [bruxism] in the USA (amplitude {A} = 1.91, p = 0.003), Canada (A = 1.91, p < 0.001), and Australia (A = 2.25, p < 0.001), and a trend towards a seasonal variation in the UK (A = 1.11, p = 0.032), with a peak in the winter months and trough in the summer months. Similarly, a statistically significant seasonal variation was found in [teeth grinding + teeth clenching] in the USA (A = 5.54, p < 0.001), the UK (A = 4.36, p < 0.001), and Australia (A = 3.11, p < 0.001), and a trend towards a seasonal variation in Canada (A = 1.53, p = 0.034). The peaks in winter and troughs in summer were reversed by 6 months in countries of northern hemisphere compared to Australia. Time series plots emphasized the consistency of seasonal trend that was ascertained in the cosinor analysis, by repeating in nearly all years.
conclusionThe preliminary evidence showed a seasonal variation in bruxism and its symptoms, with a peak in the winter months. This novel finding in bruxism epidemiology requires to be verified with clinical studies, and further researches are necessary to elucidate the potential mechanism behind seasonal variation in bruxism.
