Comparison of the group of patients with an unfavourable functional outcome (GOS 2 and 3) and the group of patients with a favourable functional outcome (GOS 4 and 5) as a function of various prognostic criteria. A criterion was considered to have a prognostic value when a statistically significant difference was observed between the 2 groups with P < 0.05 (α = 5%).
