Correspondingly, axial elongation in the right eyes during the study period was greatest in the myopia group (0.64 ± 0.10 mm), followed by the low-dose NRG-1 antibody group (0.49 ± 0.08 mm) and the medium-dose NRG-1 antibody group (0.44 ± 0.14 mm); it was lowest in the high-dose NRG-1 antibody group (0.37 ± 0.07 mm) (Table 2; Figure 2C). Here, NRG1 is linked to myopia.
