the results showed that the percentage of the ischemic zone infarcted ( % infarction ) vs the log of duration of ischemia yielded a sigmoid curve which could be linearized by probit analysis : probits of % infarction = 3.05 x log ( ischemic duration in minutes ) + 0.33 , r = 0.83 , p less than 0.01 .
