The effect of COVID-19 on visual outcome and dry eye after SMILE.
Article in Advances in ophthalmology practice and research. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Purposes: To evaluate the impact of coronavirus disease 2019 (COVID-19) on postoperative visual acuity, optical quality, and severity of dry eye disease in patients after small incision lenticule extraction (SMILE). Methods: This is a retrospective, comparative study. Patients who underwent SMILE were included and divided into two groups according to the period at the eye center of the Second Affiliated Hospital of Zhejiang University. The first group included patients who underwent SMILE before the large-scale COVID-19 pandemic in China (Group 1). The second group comprised patients who underwent SMILE during the pandemic with a confirmed infection of COVID-19 (Group 2). The visual acuity, the severity of dry eye, ocular surface disease index (OSDI), oculus keratography analysis, and individual Zernike coefficients were evaluated and compared between the 2 groups. Results: A total of 43 eyes of 23 patients and 45 eyes of 26 patients were included in Groups 1 and 2, respectively. The OSDI score in Group 2 was significantly higher than Group 1 ( Conclusions: COVID-19 infection impaired visual outcomes and aggravated dry eye severity among postoperative SMILE patients.
