Mechanical ventilation rates
The rates of mechanical ventilation were not significantly different between the two treatment arms in the ITT population, although the nebulised UFH treatment arm showed numerically lower rates of intubation (ITT population; odds ratio 0.51, 95% CI 0.16 – 1.57)(Table 8). For the MITT and PP populations, the treatment effects reached the pre-defined level of significance (p<0.1).
