More patients died 28 days after randomisation in the salbutamol group than in the placebo group (RR 1·47, 95% CI 1·03–2·08; p=0·03; table 2). Survival analysis of the primary outcome (figure 3) showed a hazard ratio of 1·56 (95% CI 1·03–2·36). Salbutamol resulted in a 10·9% (95% CI 1·0–20·4) absolute increase in 28-day mortality
