A). Demographic details of the study population. B). ATX protein levels were significantly elevated in the AH of POAG patients (n = 27) compared to cataract (control) patients (n = 27) based on Mann Whitney U test. C). The ATX protein levels in AH samples and preoperative IOP values POAG patients were significantly and positively correlated (Pearson Correlation Coefficient = 0.622, 95% confidence interval = 0.316 to 0.810, p≤0.001). D). ATX protein levels in the AH of POAG patients was significantly elevated in both males (n = 9) and females (n = 18) compared to cataract patients (males, n = 13; females, n = 13) by the multiple t-test. Within the POAG group however, the ATX protein levels did not differ between males and females. E). AH ATX protein levels were significantly elevated in the Caucasian (n = 14) and African American POAG patients (n = 13) compared to cataract patients (Caucasian, n = 22 and African American, n = 3) based on the Multiple t-test. F). No correlation was found between patient age and AH ATX protein level in the POAG group (Pearson Correlation Coefficient = 0.231, 95% CI = 0.562 to 0.164, p = 0.247). Individual dots represent results for individual patients/subjects. Black dots = cataract subjects. Blue dots = POAG patients. Data in panels B, D and E represent the median and interquartile range. Data in C and F panels represent the mean linear regression (black line) and the 95% confidence interval (black dotted line).
