Incidence and characteristics of visual symptoms. Data is summarized as absolute numbers and percentages with P-value, odds ratio (OR) and 95% confidence interval (CI) plots. For the five overall visual symptoms (the top five lines), the OR and 95% CI were calculated using the patients not experiencing the specific visual symptom as reference. For the visual characteristics (last eight), the OR and 95% CI were calculated using the opposite characteristic as reference, e.g. No supplementary symptoms as reference to Supplementary symptoms, thus generating one overall p-value, OR and 95% CI
