Lost to follow-up of patients who received intravitreal anti-vascular endothelial growth factor therapy to treat four different retina disorders in an individual center in Brazil.
Article in SAGE open medicine, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Objectives: To identify risk factors for loss to follow-up in periodic intravitreal anti-vascular endothelial growth factor injections for the treatment patients with diabetic macular edema, subretinal neovascularization, age-related macular degeneration, and retinal vein occlusion in a single eye center in São Paulo, Brazil. Methods: This was a retrospective longitudinal study that gathered information from 992 patients who required intravitreal anti-vascular endothelial growth factor drugs over 6 months. The authors included age, eye disease, laterality, monthly income, distance, and payment mode as risk factors. Results: Two hundred and seventy patients (29.93%) were lost to follow-up. Multivariate analysis showed age, monthly income, eye involvement, and type of medical assistance independently associated with loss to follow-up. The odds of loss to follow-up were greater among older patients than those less than 50 years (reference), Conclusion: Loss to follow-up is paramount because many patients may remain unassisted concerning their eye diseases. Identifying the risk factors is crucial to enforcing measures to increase adherence and the long-term success of the treatment.
