Bar charts showing comparisons between outpatient volumes in the 2019 and 2020 study periods. (Left) Error-bar chart displaying study cohorts’ ages in the two study groups. The height of the bars corresponds to the mean value, while the error bars represent the standard deviation (SD) of the data. Groups’ ages significantly differ between groups (P = 0.005). (Middle and right) Stacked bar charts showing the contribution of different sub-groups to each separate category in the two study periods. (Middle) The difference in gender prevalence was statistically significant (P = 0.022) between the two groups. (Right) The largest drop in outpatient volume was recorded in AMD patients (− 79.9%)
