^athe study Hodgson et al. 2017 [17] estimated the relationship between QoL and visual acuity using two regression models: one for the QoL associated with better seeing eye (BSE), one for the QoL associated with worse seeing eye (WSE). In the present analysis, only the second regression model was used, assuming that in clinical trials the drug treatment was always carried out on the eye with worse visual acuity
