title: Is there a difference in survival between men and women suffering in-hospital cardiac arrest?
abstract: OBJECTIVE
  To describe in-hospital cardiac arrest (CA) events with regard to sex and to investigate if sex is associated with survival.
  
  
  BACKGROUND
  Previous studies exploring differences between sexes are incongruent with regard to clinical outcomes. In order to provide equality and improve care, further investigations into these aspects are warranted.
  
  
  METHODS
  This registry study included 286 CAs. To investigate if sex was associated with survival, logistic regression analyses were performed.
  
  
  RESULTS
  The proportion of CA with a resuscitation attempt compared to CA without resuscitation was higher among men. There were no associations between sex and survival when controlling for previously known predictors and interaction effects.
  
  
  CONCLUSIONS
  Sex does not appear to be a predictor for survival among patients suffering CA where resuscitation is attempted. The difference regarding proportion of resuscitation attempts requires more attention. It is important to consider possible interaction effects when studying the sex perspective.
