Odds ratios adjusted for age, gender, and general practice throughout (except for age which is adjusted for gender and practice, and gender which is adjusted for age and practice) † Exposure variable treated as a score. ‡ Slightly lower number of respondents to this domain score, as participants responded that they had stopped going out to see films, plays, or sport events as they were not interested in doing this or due to non eyesight related reasons *Odds ratios for VA<6/18 based on 463 as 4 practices did not have drivers with VA<6/18 | |||||
