IGF1 and myopia: The results demonstrated that no significant associations between IGF-1 rs12423791 and high myopia were present in the allelic model (OR: 1.05, 95% CI: 0.96–1.14, P>0.05 in the random-effects model), the codominant model (CC vs. GG: OR = 1.11, 95% CI = 0.91–1.36, P>0.05 in the fixed-effects model; CG vs. GG: OR = 1.10, 95% CI = 0.87–1.38, P>0.05, in the random-effects model), the dominant model (CC+CG vs. GG: OR = 1.10, 95% CI = 0.86–1.41, P>0.05 in the random-effects model), and the recessive model (CC vs. CG+GG: OR = 1.08, 95% CI = 0.91–1.29, P>0.05 in the fixed-effects model).
