Text: In multivariate analyses, adjusting for randomization arm, age, baseline IOP, central corneal thickness, pattern standard deviation, and HRT disc area, the following HRT parameters were associated with the development of OAG : the '' outside normal limits '' classification of the Frederick Mikelberg (FSM) discriminant function (hazard ratio [HR] 2. 51, 95 % confidence interval [CI] : 1. 45-4. 35), larger mean cup depth (HR 1. 64, 95 % CI : 1. 21-2. 23), cup-to-disc area ratio (HR 1. 43, 95 % CI : 1. 14-1. 80), linear cup-to-disc ratio (HR 1. 43, 95 % CI : 1. 13-1. 80), cup area (HR 1. 33, 95 % CI : 1. 08-1. 64), smaller rim area (HR 1. 33, 95 % CI : 1. 07-1. 64), larger cup volume (HR 1. 30, 95 % CI : 1. 05-1. 61), smaller rim volume (HR 1. 25, 95 % CI : 1. 01-1. 54), larger maximum cup depth (HR 1. 18, 95 % CI : 1. 01-1. 36), and cup shape measure (HR 1. 18, 95 % CI : 1. 01-1. 36).
