Kaplan–Meier survival curve demonstrating progression from intermediate to advanced AMD with or without HRF. (A) Kaplan–Meier survival curve (KM curve) of the time to progression to advanced AMD. The proportion of patients who progressed to advanced AMD at 60 months is 53.8% and 19.6% in the HRF (+) and HRF (−) groups, respectively. HRF is associated with the progression and time to progression of advanced AMD (p = 2.3 × 10−4, log-rank test). (B) KM curve of the time to progression to MNV. The proportion of patients who progressed to MNV at 60 months is 47.5% and 14.2% in the HRF (+) and HRF (−) groups, respectively. HRF is associated with the progression and time to progression of MNV (p = 7.0 × 10−5, log-rank test). (C) KM curve of the time to progression to atrophy. The proportion of patients who progressed to atrophy at 60 months is 11.8% and 7.6% in the HRF (+) and HRF (−) groups, respectively. There are no significant differences between the presence of HRF and time to progression of atrophy (p = 0.96, log-rank test).
