1 · What the graph read from 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.

2 · The registry

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: There are limited studies on factors that impacted retina clinic patient outcomes during the COVID-19 pandemic. We aimed to evaluate visual and anatomic outcomes in patients with diabetic macular edema (DME) requiring anti-VEGF injections at the veterans' affairs tertiary care eye clinic in Houston, TX. Methods: Patient volume from April 2020 was compared to that of April 2019 to determine attendance changes. To evaluate outcomes, we reviewed patients with DME who had scheduled appointments during April 2020. We tracked changes in central foveal thickness (CFT) and Snellen visual acuity (VA) measurements. Patient outcomes were classified as poor (defined as worsening VA or CFT at follow-up) or good (no worsening of either at follow-up). Regression analysis identified characteristics associated with poor outcomes. Results: To prevent the spread of COVID-19, patients were called to reschedule clinic appointments. Attendance frequency decreased from 523 patients in April 2019 to 246 patients in April 2020. 134 patients met inclusion criteria (mean age of 64.7 ± 8.8 years). 19/134 of patients were seen on schedule, 89/134 had delayed appointments (average follow-up interval of 115.2 ± 50.0 days), and 26/134 were lost to follow-up. Patients with delayed appointments had higher odds of poor outcome at follow-up compared to patients seen on schedule (OR = 4.03, 95% CI: 1.14-16.92, Conclusions: On average, patients were rescheduled to a visit 2.4 months later than their usual visit. Over half these patients experienced worsening of vision or edema. This demonstrates that lapses in care result in worsening of DME. However, there is no clear association between baseline characteristics and risk of disease progression.
