The median time to study drug administration was 16.7\u2009h (25th, 75th percentiles\u2009=\u20096.5, 23.1), with significant regional variation (e.g. median of 13.0\u2009h in Asia-Pacific vs. 18.4\u2009h in North America). After risk adjustment, each hour delay in study medication after the first 10\u2009h from initial hospital presentation was associated with modestly reduced odds of dyspnoea relief [(adjusted odds ratio (OR) 0.98, 95% confidence interval (CI) 0.98\u20130.99; P &amp;lt; 0.0001]. Every hour delay in study medication was associated with modestly higher all-cause mortality or re-hospitalization (unadjusted OR 1.01, 95% CI 1.01\u20131.02; P &amp;lt; 0.001) due to pre-randomization therapies and known predictors of 30-day outcomes (adjusted P = 0.12).
