Studies concerning a computer analysis of patients with primary, secondary or stress polycythaemia.

Abstract

SummaryPreviously published hæmatological data concerning patients with primary, secondary or stress polycythæmia have been analysed by digital computer. The mathematical model utilized is presented, and the results of the analysis have been related to the clinical and laboratory findings. It is emphasized that different mathematical methods of treating the data may produce variable results. Accordingly, the results of computer analysis should be regarded critically and with an awareness of the limitations of the mathematical methods involved.Complex data are often assembled under less than ideal conditions for subsequent computer analysis. However, the present study concerning previously published hæmatological data indicates that such material may be amenable to certain statistical techniques provided that the subsequent computer results are interpreted carefully.It is further emphasized that computer analysis of any medical data must involve close cooperation between clinician and mathematician if the resultant information is to be regarded as accurate.
