BMP4 and glaucoma: No significant associations were found between TGFβ2, BMP4, and FOXC1 and glaucoma (Table 2 [A], Table 3 [A], Table 4), except between the combined group HTG+OHT and BMP4 (Table 3 [A]) where there was a weak association which did not withstand permutation testing (uncorrected p=0.040, corrected p=0.1320, OR 1.26).
