Abbreviations: CI: confidence interval; LogMAR: logarithm of the minimum angle of resolution; n: number of subjects; OAG: open-angle glaucoma; OH: ocular hypertension; SD: standard deviation.
aMean difference calculated as OAG−OH.
bSignificance of differences between the OAG and OH groups was tested using the chi-square test for categorical data and the t-test for continuous data. Fisher's exact test was used for categorical data when the expected marginal size was <5.
cMissing data for 1 subject in the OH group.
dMissing data for 1 subject in the OAG group.
e n = 266 in the OAG and n = 100 in the OH group.
fMissing data for 1 subject in both the OAG and OH groups.
gData concerning myopia were collected under medical history.
