Authors' conclusion

Based on pooled randomized trial evidence, a lower compared with a higher blood pressure target results in a reduction of mortality, atrial fibrillation, and transfusion requirements.

Further pooled results

Sensitivity analyses (incl. low risk of bias studies)

Findings mainly driven by ICU studies and treatment >24 hours; magnitude and direction similar in the majority of sensitivity analyses

AF and transfusion

Lower rate of AF and fewer patients requiring transfusion with low-pressure targets

Other secondary outcomes

No differences found
