Dear Editor:
We read with great interest the paper by Nuebel et al, “Evaluation of major adverse events of clozapine based on accordance to an international titration guideline.”

The authors concluded that more aggressive clozapine dose relationships did not increase the incidence of adverse drug reactions (ADRs) in their small chart review of mostly white males. This conclusion was drawn from the finding of an inverse correlation between the cumulative dose of clozapine in the last week of hospitalization and the probability of ADRs. However, we want to point out that this result may have been incorrectly derived
