Interestingly, in this study, uteroglobin and CHI3L1 correlated in the POAG group but not in the cataract group (POAG p = 0.006, rs = 0.624; cataract p = 0.126, rs = 0.387), which may suggest that a similar mechanism could be occurring in POAG, however, this correlation did not pass correction for multiple testing. Here, CHI3L1 is linked to open-angle glaucoma.
