COVID-19 Pandemic Lockdowns' Impact on Visual Acuity of Diabetic Macular Edema: A Large Cohort.

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
introductionThe objective of this study was to evaluate the impact of unplanned treatment gap, secondary to COVID-19 pandemic lockdowns, on visual acuity in previously treated diabetic macular edema (DME) patients.
methodsA multicenter, retrospective study of DME patients, previously treated with anti-VEGF injections, who were followed up during COVID-19 pandemic (2020) compared to pre-CO-VID-19 period (2019).
resultsA total of 634 DME patients with a mean age of 68.4 years met the inclusion criteria, 385 were assessed in 2019 (pre-COVID-19) and 239 patients assessed in 2020 (COVID-19). Baseline best corrected visual acuity (BCVA) among patients in 2019 and 2020 was 0.52 ± 0.44, 0.45 ± 0.43 (logarithm of the minimal angle of resolution, respectively). There was no significant difference between the years 2020 and 2019 in baseline BCVA (p = 0.07). Mean number of anti-VEGF injections was significantly lower (5 vs. 6, p < 0.01), with a major lower ratio of injections per patient in the COVID-19 first lockdown period (March-June 2020) in the COVID-19 group. Baseline BCVA (p < 0.01) was the only significant predictor of final BCVA. Number of injections, age, gender, and the year were not found as predictors of final BCVA.
conclusionsIn a large cohort of DME patients, an unplanned delay in treatment with anti-VEGF injections for 2-3 months, due to COVID-19 pandemic lockdown, had no significance impact on visual acuity. For most patients, returning to routine treatment regimen was sufficient for maintaining BCVA.
