Examples of “2DBIA” visualization of bioimpedance examination by 8 parameters, with centile lines, arranged in two-dimensional graphs.Every point corresponds individual examination data. Dynamic observation of one patient is presented by line connected points. The arrow marks to the first examination point.A. Data on a group of professional rugby players, 97 men 20–25 years old.B. Data on a group of diabetic patients 60–70 years old. Pink points belong to 59 non-sarcopenic patients, blue points belong to 7 sarcopenic patients.C. Data on a healthy pregnant woman 33 years old from 11th to 37th weeks of gestation. The points correspond to 11th (marked with an arrow), 16th, 22nd, 26th, 30th, 34th, 37th weeks of gestation.D. Data on a pregnant woman 29 years old with a preeclampsia. Examinations were made daily from 30th week of gestation to the delivery at the 32nd week of gestation and on 2nd, 3rd, 4th, 5th, 8th, 9th, 10th, 11th, 12th and 15th day postpartum.E. Data on fat mass reduction in a 52 years old woman without any recorded associated diseases.F. Data on an intensive care unit patient with edema.
