Reshaping the Burden of nAMD: National, Regional, and Global Prevalence of MNV3 and Its Correlation With Life Expectancy—The RAP Study, Report 7
Bibliographic record
Abstract
Background: To report the global distribution of macular neovascularization type 3 (MNV3) and to redefine the associated burden of neovascular age-related macular degeneration (nAMD). Methods: A total of 4652 patients with treatment-naïve nAMD were included. MNV3 was diagnosed using multimodal imaging methods. The prevalence of MNV3 in each country, region, continent and worldwide was calculated. The correlation between the prevalence of MNV3 and life expectancy in each country was estimated. Continent prevalence data was compared using a logistic (binomial) generalized linear mixed model (GLMM). Results: Our analysis revealed 4652 nAMD eyes from 47 countries, 575 (12.4%) of which had MNV3. In North America, the highest percentage was in Canada (17.6%), followed by the USA (11.5%). In Europe, the highest prevalence (23.4%) was in Austria and the lowest (4.3%) in Russia and Croatia. The prevalence in Asia, South America, and Australia was 6.6%, 9.4%, and 13.7%. A significant positive correlation was found between the MNV3 prevalence and life expectancy in 20 European countries (r = 0.63, P < 0.003). The GLMM revealed significantly lower odds for observing MNV3 in Asia compared to Europe (P < 0.01). No significant difference was observed in any other continent pair. The prevalence in Western Europe and Mediterranean region was higher than in Eastern Europe and the non-Mediterranean region (18.6% vs. 9.6%, P < 0.001; and 17.5% vs. 12.6%, P = 0.001, respectively). Conclusions: MNV3 is more prevalent in Western and Mediterranean regions, likely because of higher life expectancy and a lower percentage of Asian ethnicity. AREDS supplements and the Mediterranean diet may not provide prophylactic benefits against the development of MNV3. The unique distribution pattern of MNV3 and its correlation with life expectancy should be considered in nAMD research to ensure adequate representation of MNV3 patients in clinical trials.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
