Continuity of care and risk of vision loss in patients with newly developed macular degeneration.

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
purposeNeovascular age-related macular degeneration (AMD) is a major cause of vision loss. Effective treatment requires sustained care, which may be influenced by continuity of care (COC). Understanding this association is crucial for improving patient outcomes. We investigated the association between COC and the risk of visual impairment in patients newly diagnosed with neovascular AMD.
methodsThis nationwide cohort study sourced data from the South Korean National Health Insurance Service database (2014-2021). In total, 15 563 (6210 females) newly diagnosed patients with neovascular AMD were included. The COC index, based on the frequency of ophthalmology visits over the first 2 years post-diagnosis, was assessed; a threshold of 0.75 was used to define good continuity. The primary outcome was visual impairment. Statistical models were used to assess the association between COC and the visual impairment risk, with adjustment for relevant confounding variables.
resultsPatients with a bad COC index had a significantly higher cumulative incidence (6.86% vs. 4.78%) and a higher incidence rate of visual impairment (909 vs. 704 cases per 100 000 person-years; 95% confidence interval, 764.0-1080.4, p < 0.001). This elevated risk was especially notable for female patients, patients aged ≥70 years, and patients with lower comorbidity burdens.
conclusionsPoor COC is associated with increased visual impairment risk in patients with neovascular AMD. Strategies to improve COC may reduce this risk, particularly among older adults and high-risk groups.
