raised by Drs Kario and Pickering, we do not have any data regarding
the status of hypertensive treatment at the time of onset of the stroke
in the patients we studied. We designed this study primarily as a study
of the predictive value of baseline risk factors, not as a longitudinal
study of time-dependent risk factors. The best that we can offer is
that 41 patients (20 with normal oxygen extraction fraction and 21 with
increased oxygen extraction fraction) were taking antihypertensive
medication at the time of entry into the study.
