The negative impact of COVID-19 pandemic on age-related macular degeneration patients treated with intravitreal bevacizumab injections.
Article in International ophthalmology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
purposeCOVID-19 emerged in the end of 2019 and was declared a worldwide pandemic shortly after. Social distancing and lockdowns resulted in lower compliance in intravitreal injections and office visits. We aimed to assess clinical outcomes among patients who missed these visits compared to those who arrived as planned.
methodsPatients who missed or were late to office visits or intravitreal injections were defined as non-adherent and were compared to adherent patients. Our main outcomes were the need for subsequent injections, mean change in best-corrected visual acuity (BCVA), and central macular thickness (CMT).
resultsThis study included 77 patients (24 adherent and 53 non-adherent). The mean BCVA remained stable during the study period for the adherent group (p = 0.159) and worsened in the non-adherent group (p < 0.001). Changes in CMT and maximum thickness were not significant for either group. A higher proportion of patients in the non-adherent group needed subsequent intravitreal injections (49% vs 20%, p = 0.014).
conclusionThe findings demonstrate the negative implications of the COVID-19 pandemic and the effect of deferring bevacizumab injections among individuals with age-related macular degeneration. This emphasizes the importance of a scheduled follow-up, also during a pandemic.
