Prevalence estimates are medians (95% credible intervals in parenthesis) of the posterior distributions for predicted prevalence from the Bayesian multilevel binomial logistic regression of the log odds of myopia adjusting for ethnic specific associations with age, ethnic specific associations with survey year (for white, East Asian and South Asian children, only) and environmental setting. The multilevel model takes into account that some study populations provide only one age-specific estimate whereas others contribute data for several age groups.
Estimates correspond to urban populations.
*Survey year fitted in the model.
†Estimate at age 16.5 years (upper limit of available data).
‡Estimate at age 7 years (lower limit of available data).
§Mean survey year weighted by study population size.
¶Estimate at age 12.5 years (upper limit of available data).
**Estimates correspond to rural populations as there were no data in an urban setting for this ethnic group.
††Estimate at age 14.5 years (upper limit of available data).
