Clinical studies
Clinical studies form the scientific basis for analyzing body composition using
this device. The study results are integrated in the device software in the form
of reference values.
For some analysis parameters, the reference used depends on the patient's
ethnicity. The device automatically uses ethnicity-dependent references to
suit the corresponding entry in the seca patient file

a. In the USA, a study was conducted on 130 healthy adults of different ethnicities. The aim of the study was to validate the para -
meters determined using seca formulas against clinically established reference methods. The results of this comparative study are
shown in the table above. The table shows the standard deviation (SEE) by ethnicity for the parameters determined using seca's
in-house formulas.
