Abstract
PURPOSE: To conduct a meta-analysis on the rates of myopia progression in urban children of Asian and predominately European ethnicities who are corrected with traditional single-vision spectacles. METHODS: A search of the National Library of Medicine's PubMed literature database for articles on myopia progression was conducted using the terms "myopi*progression" and MeSH terms "myopia" and "disease progression," and limited to publications from January 1990 and only for articles reporting data for humans <16 years of age. Studies were excluded if they were non-randomized, did not use cycloplegic autorefraction, had a sample size <30 individuals, examined high myopia (worse than -6.0 D) or special subject groups, presented myopia as part of a syndrome or condition, were retrospective, or used controls wearing optical corrections other than spectacles. RESULTS: Of 175 articles identified, 20 remained after applying the exclusion criteria. The estimated myopia progression at a mean age of 9.3 years after 1 year of follow-up was -0.55 D [95% confidence interval (CI), -0.39 to -0.72 D] for populations of predominantly European extraction and -0.82 D (95% CI, -0.71 to -0.93 D) for Asians. The estimated progression rates were dependent on baseline age, with decreasing progression as age increased. The rates also varied with gender. For an average baseline age of 8.8 years, estimated annual progression (combined ethnicities) was -0.80 D/yr for females (95% CI, -0.51 to -1.10), and a significantly slower (p < 0.01) -0.71 D/yr for males (95% CI, -0.42 to -1.00). CONCLUSIONS: In children wearing single-vision spectacles, higher myopia progression rates were found in urban Asians compared with urban populations of predominantly European descent. Younger children and females demonstrated greater annual rates of progression of myopia.

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 it
