Epidemic retinitis during the COVID-19 pandemic.
Observational study in Indian journal of ophthalmology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Purpose: To study the impact of the novel coronavirus disease-2019 (COVID-19) pandemic on incidence, seasonal variation, clinical presentation, and disease outcome of epidemic retinitis (ER) and to compare clinical outcomes with positive and negative COVID-19 serology. Methods: This is a retrospective, observational study conducted at a tertiary eye care hospital from August 2020 to June 2022. A graph of ER cases against the month of presentation was compared with the graph of the COVID-19 pandemic in the same region. Cases presented before COVID-19 vaccination, with positive COVID-19 serology (Group 1) were compared with cases with negative serology (Group 2). Results: One hundred and thirty-two cases of ER were seen. The least number of cases were seen during and immediately after the peak of the pandemic (May 2021-August 2021). COVID-19 serology was positive in 13 (22 eyes)/60 (21.6%) unvaccinated cases. Along with COVID-19, positive serology for other ER etiologies was seen in 5/13 cases (38.4%). All patients received oral doxycycline with/without steroids. Groups 1 and 2 included 22 and 21 eyes of 13 cases each. Macular edema resolved in 43.6 and 32 days in groups 1 and 2, respectively. Retinitis resolved at 1 month in both groups. Corrected distant visual acuity was 20/50 and 20/70 at the presentation, which improved to 20/20 and 20/25 in groups 1 and 2, respectively. Mean and median follow-up was 6 months and 4.5 months, respectively, in both groups. No complications or recurrences were seen. Conclusion: No significant impact of the COVID-19 pandemic on ER was observed.
