Abstract
Introduction. Chernoff faces, invented by Herman Chernoff in 1973, is a method of displaying multivariate data in the shape of a human face. Aim. The aim of the study was to characterize the group of adolescents with hypertension identified in the course of screening tests and to display it with the aid of Chernoff faces. Material and methods. The study group consisted of 690 middle and high school students aged 15-17, from randomly selected Warsaw and sub-Warsaw schools, 366 boys and 324 girls who underwent screening tests (I stage). Among them 40 students were diagnosed with arterial hypertension and qualified for diagnosis in the Department of Cardiology (II stage). Results. The results were presented graphically using Chernoff faces. Conclusions. Chernoff faces show the characteristics of small groups of patients differing from each other by a large number of analyzed parameters in much more efficient, effective and interesting way than standard charts and tables.
