The effects of achieving hypothermia early in a heterogeneous population of patients with cardiac arrest.

Research output: Contribution to journalArticle

Abstract

In a recent article Wolff et al. (2009) [1] present highly interesting results bearing on how timing of therapeutic hypothermia might affect outcome. However, some of their analyses are unadjusted for heterogeneities in the patient population, while others indicate a statistical model break-down. Moreover, the time from cardiac arrest to return of spontaneous circulation is recorded but not included as a potential covariate in the multivariate logistic regression, which is unfortunate considering that many studies have found it to be an important predictor of outcome. It is well-known that in observational studies it is important to adjust for all important covariates, not only statistically significant ones. Hence, we caution against drawing firm conclusions from this study.
