Association between Serum Potassium with Risk of Onset and Visual Field Progression in Patients with Primary Angle Close Glaucoma: A Cross-Sectional and Prospective Cohort Study

Figure 3

Kaplan-Meier curves for PACG patients divided by the median of potassium level. Plot of Kaplan-Meier depicts the probability of no progression in PACG patients in each group. The number of PACG patients without progression in each group was shown below five follow-up time points. Kaplan-Meier curves between lower and higher baseline levels of potassium in all PACG subjects (a), in male subjects (b), and in female subjects (c).
