A separate 2013 met-analysis confirmed these findings, showing that the association between the GSTM1 null genotype and risk of POAG was not statistically significant in ED populations (OR 1.13, 95%CI: 0.69–1.84, p = 0.64) or Latin American populations (OR 1.09, 95%CI: 0.62–1.92, p = 0.77), but was statistically significant in an East Asian population (OR 1.41, 95%CI: 1.04–1.90, p = 0.026) [102]. The gene discussed is GSTM1; the disease is open-angle glaucoma.
