Steroid therapy was associated with death, both in crude analysis (33.7 vs. 16.8%; hazard ratio, 2.4; 95% CI, 1.3\u20134.3; P = 0.004) and after propensity score\u2013adjusted analysis (adjusted hazard ratio, 2.82; 95% CI, 1.5\u20135.4; P = 0.002), controlling for an admission severity Simplified Acute Physiology Score, version 3, greater than 50, initial administration of vasopressors, and immunodepression. Early therapy (\u2264 3 d of mechanical ventilation) appeared more strongly associated with mortality than late administration.
