The effect of COVID-19 pandemic on the attendance and clinical outcomes of patients with ophthalmic disease: A mini-review.
Article in Metabolism open, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 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
The outbreak of COVID-19 was followed by a rapid spread leading to its declaration as a pandemic in a short time. The transmission through aerosols and direct contact with infected individuals forced the application of strict safety protocols and rearrangements in the activities of different healthcare systems around the world. Ophthalmology healthcare workers are highly exposed to viral infection and therefore adjustments were made to ensure the safety of patients and health providers by performing only urgent treatments. The suspension and delay in regular follow-up visits and the lower number of patients recorded during the lockdown period due to restrictions and patient anxiety led to severe consequences in the clinical and anatomical outcome affecting the overall prognosis. The current review aims to summarize the effect of the lockdown policies in the number and profile of patients that attended the ophthalmology clinics from different countries and analyze the effect of the pandemic in terms of vision and patient functionality. The effects of the pandemic included a reduction in the number of appointments, cancellations of non-emergency conditions and delays of surgical interventions. These had a negative effect in terms of visual outcomes.
