Kaplan-Meier plot: Time to any complication (including both minor and severe complications as equivalent statistical events) following Herbst incorporation, by gender (male/female). The log-rank test analyzed potential differences between the survival times for the two genders. No statistical significant differences were found in the data (p = 0.4). The median time to complication was reached neither for males nor females within the observational time frame. The 200 day survival rate was 53 % for males and 83.7 % for females, and 53 % or 59.8 % for 300 days, respectively
