COVID-19 pandemic: Impact on the rate of viral conjunctivitis.
Article in Archivos de la Sociedad Espanola de Oftalmologia, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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
objectiveThe COVID-19 pandemic led Spain to order a state of alert with the cessation of non-essential activities on 14 March 2020, and to implement public health interventions (such as home confinement) and other health recommendations to prevent the spread of the SARS-CoV-2 virus (hand washing and the obligation to wear face-masks). These factors could have influenced the rate of viral conjunctivitis.
methodIn this retrospective, noninterventional, descriptive study, the incidence of viral conjunctivitis in an emergency department of a national hospital is compared over two distinct time periods: pre-COVID (13 March-30 September 2019, one year before the start of the pandemic) and COVID (13 March-30 September 2020).
resultsIn the first period there were 436 cases of conjunctivitis, of which 168 (38.5%) were confirmed cases of viral conjunctivitis 168 (38.5%), while in the second period there were 121 recorded cases, of which the most frequent were allergic and traumatic (23 cases; 19% each group), bacterial (15 cases; 12.3%) and viral (15 cases; 12.3%). The diagnosis of viral conjunctivitis is the one that suffered the most significant relative reduction (48.5%), while other types of conjunctivitis hardly changed their relative frequency between these two periods of time.
conclusionsViral conjunctivitis is the most frequent infectious disease of the eye and has a transmission rate similar to that of coronavirus, so the measures implemented could positively affect its incidence.
