Linear regression analysis of changes of the clinical score at the follow-up as compared with the preoperative scores was not related to the preoperative CCI. The regression line is shown and in addition the individual data visualized as jitter plot. The jitter plot is like a scatter plot but adds random noise to better see the information contained in the data, when there is a lot of overplotting.
