Frequency distribution of the BIA records (n=2,429,977) by the Federal subjects of Russia.
Fig.3
Frequency distributions of the BIA records (n=2,429,977) by the month and year of measurement (upper panel) and the time of day (lower panel).
Fig.4
Frequency distribution of the BIA records (n=2,429,977) by the year of birth of the measured persons (upper panel) and of the total number of HCs according to the number of BIA measurements (lower panel).

Histograms of the resistances R50: left – females (n=1,607,906), right – males (n=822,071).
Fig.7
HCs’ reference data on the phase angle at 50 kHz according to age: the medians and interquartile range (blue lines). Upper panel – females (n=1,607,906), lower panel – males (n=822,071). The red lines show estimated mean values according to meta-analysis of pooled data from 46 studies [9].
