Kaplan–Meier survival plots for the probability (y-axis) of a tail biting outbreak continuing, where higher survival probability represented a higher chance that the tail biting outbreak was continuing and not controlled. (a) Number of interventions used, blue solid line: outbreaks with one intervention used, red dashed line: two interventions, and green dashed-dotted line: three interventions. (b) The outbreaks that were successfully controlled with one intervention: blue solid line: adding ropes, red dashed line: removing biters, green dashed-dotted line: removing victims.
