Correlation analysis between parameters in cases using Spearman correlation coefficient (rho). Indeed, the p-value is recorded under the correlation coefficient. Accordingly to the study methodology, LogMAR BCVA has been used to record BCVA values. In cases, the correlation between BCVA and Age is rho = 0.47 (p = 0.050), indicating a moderate positive correlation. This suggests that BCVA values also tend to increase as age increases, meaning that older individuals tend to have worse visual acuity. The correlation between BCVA and CMT is rho = 0.62 (p = 0.006), which shows a strong positive correlation. This indicates that as central macular thickness (CMT) increases, BCVA values also increase, corresponding to a deterioration in visual acuity.
