Curve profile explanation: Note that, since the discontinuation criterion allowed a 90-day gap, determining the therapy discontinuation rate was methodologically restricted to 90 days after the observation start point. However, several censored observations (that influenced the survival chances) were present at that point, causing the curve profile to sharply drop at the first therapy discontinuation value.
