  1. Data are presented as means ± standard deviations where applicable. Analysable RP group: RP patients with analysable quality of the optical coherence tomography angiography images. Non-analysable RP group: RP patients with non-analysable quality of the optical coherence tomography angiography images. RP = retinitis pigmentosa, LogMAR VA = logarithm of minimal angle of resolution visual acuity. In a,b, and c, data were missing for 14, 2, and 12 eyes, respectively. *P < 0.05, t-test or chi-square test compared to the analysable RP group.
