Review Meta AnalysisMortality benefit of vasopressor and inotropic agents in septic shock: A Bayesian network meta-analysis of randomized controlled trials.
The choice of vasopressor in septic shock has been a matter of debate. The purpose of this study was to systematically review overall evidence of vasopressor and inotropic agents in septic shock using a Bayesian network meta-analysis. ⋯ Our results support the use of NE with or without low-dose vasopressin as the first-line vasopressor therapy in septic shock. No concrete evidence exists to support the use of EPI over dopamine as the second-line agent or the addition of an inotropic agent.

Review Meta Analysis Comparative StudyDo the observational studies using propensity score analysis agree with randomized controlled trials in the area of sepsis?
Sepsis is a leading cause of mortality and morbidity in the intensive care unit, and many studies have been conducted aiming to improve its outcome. Randomized controlled trials (RCTs) and observational studies using propensity score (PS) method are commonly used for this purpose. However, the agreement between these two major methodological designs has never been investigated in this specific area. The present study aimed to compare the effect sizes between RCTs and PS-based studies. ⋯ Our study shows that PS studies tend to report larger treatment effect than RCTs in the field of sepsis, indicating the difference between efficacy trials and effectiveness studies.
