If the curves were truncated, such that the last four provocative doses were omitted from the analysis, the CGD fit still yielded plateau values; the mean difference from the measured plateaux, in % of the measured plateau values, was -2.6% (SD 18.2). In only three out of the 10 cases did the Hofstee equation yield plateau values with a deviation from 'measured' < 47% of the measured value.(ABSTRACT TRUNCATED AT 250 WORDS)
