CCNDBP1 and amyotrophic lateral sclerosis: Partial bivariate correlation analysis (correcting for age and ΔFS) for the ALS patients revealed a significant thickening of the RNFL (r = 0.37, p = 0.034) and GCIP (r = 0.40, p = 0.021) with disease progression within 12 months, while the RNFL declined with time (r = −0.41, p = 0.037) after one year.
