Tx seemed not to affect color vision, with P-values of.79 in the univariable analysis (−0.03, 95% CI [−0.30; 0.39]) and 0.86 in the multivariable analysis (−0.03, 95% CI [−0.03; 0.27]; other independent variables in the model: age, diabetes mellitus, hypertension, aromatase inhibitors). This evidence concerns the gene CYP19A1 and hypertensive disorder.
