Notes
Reason visual acuity measurement (right eye) was not performed (entered as free-text by a UK Biobank Staff member).
This field was created by post-hoc coding the free-text reasons entered during the assessment centre visit. The encoding used was constructed after the data had been examined to determine suitable representative groupings.
