| The Short Form-36 Health Survey | The 35 items of SF-36 quality of life scale were summarized into 8 dimensions. According to the influence degree of each item on the quality of life, the corresponding weight was given, and each dimension was converted into 100 points. The higher the score, the better the functional status and the higher the quality of life. | at the 0-week |
