In PLoS Medicine, volume 3, issue 12, doi:10.1371/journal.pmed.0030477:

In the Methods and Findings section of the Abstract, the figures 18/60 in the following sentence are incorrect and should read 6/18 to be consistent with what is in the main text of the article:

“Prevalence of blindness (presenting VA of less than 3/60 in the better eye) was 4.1% (95% confidence interval [CI], 3.4–4.8); prevalence of low vision (presenting VA of at least 3/60 but less than 18/60 in the better eye) was 7.7% (95% CI, 6.7–8.7); whereas prevalence of monocular visual impairment (presenting VA of at least 18/60 in better eye and VA of less than 18/60 in other eye) was 4.4% (95% CI, 3.6–5.3).”

Please note that this error does not change the data or the conclusions in the paper. It is an error in the abstract only.
