Choroidal vascularity ındex findings ın patients recovered from mild course COVID-19 pneumonia.
Article in International ophthalmology, 2025. 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
purposeTo assess the choroidal vascularity index (CVI) in individuals who have recovered from moderate pneumonia caused by COVID-19, using enhanced depth imaging optical coherence tomography (EDI-OCT).
methodsThis study included 43 patients who had recovered from SARS-CoV-2 infection with mild pneumonia (Group 1-COVID group), as well as 45 healthy individuals (Group 2- healthy control group). The study comprised COVID-19 patients who fully recovered from COVID-19 pneumonia. These patients were assessed 6 months after their pneumonia had totally resolved. The measurements were acquired via EDI-OCT investigations of the choroidal structures. The primary measure of interest was the CVI, which is defined as the ratio of the luminal area (LA) to the total choroidal area (TCA).
resultsPatients from Group 1 (COVID group) who had totally recovered exhibited significantly higher mean TCA, stromal area (SA), and LA compared to patients from Group 2 (control or healthy group). The two groups did not show a significant difference in CVI (p = 0.080).
conclusionChoroidal vascularity index can reveal the choroidal vascular physiology in patients who have fully recovered from COVID-19 pneumonia. EDI-OCT can be utilized to evaluate choroidal vascular alterations, serving as a non-invasive indicator for early vascular impairment following SARS-CoV-2 infection.
