Classification systems for the severity of a complication.
We compare numbers from our study (Zurich), Milano [25] and Buenos Aires [8]. Clavien Dindo classification system CDG [12]; Landriel scheme [8].

(A) Distribution of severity in the Clavien Dindo classification system CDG. (B) Karnofsky Performances Status Scale (KPS) as a function of severity of the complications (ρ = -0.3, slope -6 KPS percentage points per increment of CDG). (C) Duration of hospital stay after surgery (ρ = 0.4, slope 1.5 days per increment of CDG). (D) Distribution of KPS for patients with and without complications (adverse event AE).
