Real-World Outcomes of Intravitreal Aflibercept for Neovascular Age-Related Macular Degeneration: A Large-Scale Postmarketing Surveillance in Korea.
Article in Clinical ophthalmology (Auckland, N.Z.), 2021. 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 investigate the efficacy and safety of intravitreal aflibercept (IVT-AFL) in Asian patients with neovascular age-related macular degeneration (nAMD) in a real-world clinical setting. PATIENTS AND
methodsIn this analysis of a prospective, regulatory, postmarketing surveillance study for IVT-AFL, 3115 patients with nAMD were included and followed for 8 months. The mean changes in best-corrected visual acuity (BCVA) and central retinal thickness (CRT) were analyzed using last observation carried forward method. A post hoc subgroup analysis and a multivariate logistic regression analysis were also performed to assess factors related to treatment outcomes.
resultsMean BCVA improved from 0.62 to 0.51 logarithm of minimum angle resolution and mean CRT decreased from 383.3 to 289.7 μm, with a mean of 3.4 injections during the 8-month follow-up. In the subgroup analysis, patients who had received 3 initial monthly doses had significantly better anatomical improvements than those treated as needed. Patients with confirmed polypoidal choroidal vasculopathy (PCV) had significantly better anatomical improvements and better visual recovery than those with other types of nAMD. The multivariate regression analysis demonstrated that age, injection number, PCV, and baseline BCVA were significantly associated with higher odds of gaining 3 lines at 8 months, and sex, injection number, PCV, and baseline CRT were associated with CRT ≤250 µm at 8 months. No new safety findings were identified.
conclusionIVT-AFL was effective and well tolerated in a real-world setting with a large number of Asian patients with nAMD. Number of injections and PCV were important determinants for improved treatment outcomes.
