Ocular-symptoms-related Google Search Trends during the COVID-19 Pandemic in Europe.
Article in International ophthalmology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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 correlation between the daily relative search volume (RSV) of keywords related to coronavirus and ocular symptoms, and the numbers of the daily coronavirus disease 2019 (COVID-19) new cases and new deaths in Europe using Google Trends (GT).
methodsThe RSVs of the selected keywords related to coronavirus and ocular symptoms between 24 January and 1 June 2020 in the United Kingdom, Spain, Italy, Germany and Turkey were accessed from GT. The numbers of daily COVID-19 new cases and new deaths in the same time interval in the aforementioned countries were compared with the RSVs of the keywords and terms.
resultsThe United Kingdom, Spain, Italy, Germany, and Turkey were the most affected countries from the COVID-19 pandemic in Europe. In these countries, statistically significant and strong correlations were found between the daily RSVs of most keywords related to coronavirus and ocular symptoms, and the daily numbers of COVID-19 new cases and new deaths ranging from 0.175 to 0.807.
conclusionsOcular symptoms are not the frequent signs of COVID-19, but the ocular surface is a possible route for the transmission of COVID-19. The preliminary outcomes of this study demonstrated that there are significant correlations with the ocular symptoms and COVID-19. The news about the relation of eye and COVID-19 in the mass media may have influenced the Google internet search activity of the public for ocular symptoms.
