Event-free survival (EFS) rates according to immunohistochemical grade. (A) The probability of EFS according to the gelsolin expression. The EFS was 94.7% for LEG patients and 78.6% for HEG patients. The difference was not statistically significant according to the log-rank test (P=0.222). (B) The probability of EFS in terms of MMP positivity. EFS for the negative group was 96.6%, while that of the positive group was 57.1%, a statistically significant difference according to the log-rank test (P=0.002).
