Table 5. Cox multivariate analysis of prognosis of patients with ARDS.

The NGS group had a better prognosis than no-NGS group (P = 0.005). Those with a shorter stay in the ICU (P = 0.037), and lower APACHE II before treatment (P = 0.016) and SOFA scores before treatment (P = 0.003) had a better prognosis.
