Authors' conclusion

The systematic and short-term administration of cisatracurium in patients with moderate-to-severe ARDS appears to confer greater survival benefit in those with a higher baseline life expectancy.

Primary result

As reported in the abstract

Estimated survival, age <60 years with non-fatal McCabe score (subgroup, N = 130)

Placebo

0.63

n = 62

Cisatracurium

0.93

n = 68

Further findings

Estimated survival, PaO2:FiO2 > 100 mmHg at inclusion (subgroup, N = 98) · day 90 — Cisatracurium
0.92

Survival, rapidly or ultimately fatal McCabe prognosis (subgroup)

Probability of survival did not differ substantially between placebo and cisatracurium

Daily probability of remaining mechanically ventilated, age ≥ 60 years (subgroup, N = 158)

Not influenced by any covariate, including cisatracurium
  • Confirmed by simulations
