Reductions in 30-day mortality rates failed to reach significance in all three studies, but it is noticeable that a mortality reduction of 54% in the current study (RR 0.46, 95% CI 0.20–1.08; p = 0.07) is closer to a significant effect than within ICU populations (RR 0.90; 95% CI 0.69–1.16; p = 0.41) [ 18 ].
