biostudies-literatureUnknown9Zheng WH<h4>Objective</h4>Bioelectrical impedance-derived phase angle (PA) has exhibited good prognostic values in several non-critical illnesses. However, its predictive value for critically ill patients remains unclear. Thus, we aimed to perform a systematic review and meta-analysis to investigate the relationship between PA and survival in such a patient population.<h4>Materials and methods</h4>We searched for relevant studies in PubMed, Embase, and the Cochrane database up to Jan 20, 2022. Meta-analyses were performed to determine the association between the baseline PA after admission with survival. We further conducted subgroup analyses and sensitivity analyses to explore the sources of heterogeneity.<h4>Results</h4>We included 20 studies with 3,770 patients. Patients with low PA were associFrontiers in medicine1059747https://www.ebi.ac.uk/biostudies/studies/S-EPMC9868673biostudies-literaturePrognostic role of bioelectrical impedance phase angle for critically ill patients: A systemic review and meta-analysis.PMC9868673Zhao YHYao YZheng WHHuang HBfalsePrognostic role of bioelectrical impedance phase angle for critically ill patients: A systemic review and meta-analysis.<h4>Objective</h4>Bioelectrical impedance-derived phase angle (PA) has exhibited good prognostic values in several non-critical illnesses.
