In Reply Mr Stewart raises the concern that time-interval reporting during in-hospital cardiac arrest may not be fully accurate but says that the comparisons between intubation and no intubation “still should be valid.” Although we recognize that time intervals during cardiac arrest may have some degree of inaccurate reporting,1-3 we agree with Stewart that this is unlikely to affect our findings, as this misclassification is likely undifferentiated (ie, not related to outcomes).4 Presumably, inaccurate data would have tended to bias the data analysis to the null (ie, minimize the likelihood of demonstrating a difference between the 2 groups). Like Stewart, we welcome initiatives to further improve time recording during in-hospital cardiac arrest, such as tablet-based recording.2,3
