Impact of Coronavirus Disease 2019 on Intravitreal Antivascular Endothelial Growth Factor Injection Rates in Nigerians.

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
Aim: To quantify the impact of coronavirus disease 2019 (COVID-19) on the rate of intravitreal antivascular endothelial growth factor (VEGF) injections (IVI) in eye hospitals in Nigeria. Materials and Methods: A retrospective, observational, comparative study. The IVIs given 12 months before (pre-COVID) and 12 months after the first announcement of the COVID-19 lockdown (COVID) in Nigeria in four hospitals were used as the sample for this study. All eyes were treatment naïve. We determined the total number of all anti-VEGF injections, the number given for each indication, and the number of each type of the three anti-VEGFs given. A comparison of the presenting vision in IVI eyes between the two eras and the visual outcome of the IVI treatment was made. Data were analyzed using the SPSS version 22 to determine statistical significance. Results: Male/female ratio, pre-COVID 63.4%/36.6% and COVID 58.6%/41.4% ( Conclusion: COVID-19 significantly reduced the number of eyes and IVIs. Eyes had worse presenting visual acuity during the COVID era; however, treatment outcome was comparable between COVID and pre-COVID eras.
