The cohort dynamic changes of the S₂₄ score during the 80 h prior to intubation. Patients from the intubated group are in red. The plain thick line is the mean and the fine lines correspond to the 25%–75% confidence interval. The green area represents the non-intubated group; the dashed thick line is the mean and the fine lines correspond to the 25–75% confidence interval. The S₂₄ score discriminates both groups at least 80 h before intubation. We noted a net increase in S₂₄ score at 24 h prior to intubation.
