 1. The numbers in parentheses indicate that the number of aneurysms is divided by the subtype to classify the total number of aneurysms
 2. Through statistical analysis, the total variation of X  98.5, V 15, P < 0.005; linear regression  component X 74.8, v 1, P < 0.005; deviation from linear regression  component X 23.7, V 14, P 0.025–0.05. The linear regression component and the deviation of linear regression all have statistical significance. It can be considered that there is a correlation between the type of tumor neck and the way of clipping and it is a linear relationship
