Treatment Regimens with Ranibizumab in Neovascular Age-Related Macular Degeneration: Real-World Results from the PACIFIC Study.
Article in Clinical ophthalmology (Auckland, N.Z.), 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
Introduction: Intravitreal anti-VEGF is the gold standard for treating neovascular age-related macular degeneration (nAMD). The treatment success depends not only on drug efficacy but also on regimen feasibility for physicians and patients. The implementation of different regimen might lead to varying outcomes. "Treat-and-extend" aims to minimize undertreatment with injections at each visit and tailored intervals. This study investigates the utilization and effectiveness of ranibizumab in nAMD, focusing on different treatment regimens in real-world settings. Materials and Methods: The PACIFIC study, a non-interventional, prospective, multicenter study, included nAMD patients treated with ranibizumab at 185 sites across Germany, the Netherlands and Switzerland. Over 24 months, functional and morphological outcomes were documented for 3051 patients over 24 months, highlighting the practiced treatment regimens. Results: A pattern of an observational approach with nevertheless increasing interval extension prevailed (70.4%, 1028 pre-treated; 68.6%, 1090 treatment-naïve patients), emerging as the preferred strategy within the first 3 months. Across all regimens, the average number of injections was comparable (mean ± SD: 7.34 ± 5.30 in pre-treated; 7.26 ± 4.70 in treatment-naïve patients). The treat and extend regimen, however, demonstrated superior effectiveness in improving visual acuity, particularly among treatment-naïve patients (number of injections: 7.89 ± 5.54 pre-treated; 9.54 ± 5.42 treatment-naïve patients). Conclusion: Over 2-year observational period, the treat and extend regimen emerged as a highly effective approach, particularly for those newly diagnosed, with a low risk of undertreatment. Despite its benefits, an unconscious shift to a observe-and-extend or "monitor-and-extend" approach occurred early in treatment, highlighting the need for tailored approaches to optimize patient outcomes in clinical practice.
