Our logistic regression models also incorporated the following predictor variables with the controls acting as the reference group: (i) age, (ii) gender, and (iii) maximum IOP, except in the HTG subgroup where maximum IOP was not included;

^*Significant with Bonferroni correction:

^aP < 0.01

^bP < 0.008.
