Response letter to “Quality of evidence for multivariate analysis to keep stable estimates”

Abstract

We thank doctor Kawada for [1] his interesting observations. However, it must be remarked that some methodological problems were clearly recognized in our paper. In the study limitations we reported that our sample size was relatively small and although we found no differences in the rates of death, myocardial infarction in patients treated with or without abciximab during rescue angioplasty after a clopidogrel loading dose of 300mg, the study was not sufficiently powered to show differences in these clinical events [2].
