Although it probably will not stay there, for the first time the set of patients I am following achieved sufficient days to exceed the 'maximum' life expectancy . . . the data set has deficiencies such as inadequent date specifications and patients who have not been heard from in a long time. I detected several of these long lost cases recently; although most did not change the data much, some did. I am currently reviewing the data set from the point of view of 'false positive' . . . the chance these results are 'false positive' is? . . . I expect it to be small, I am hoping it will be smaller than one would likely guess.
