As exemplified by iron deficiency anemia, the study was made of effect
of iron deficiency on interdependence of immunity parameters. It is n
oted that patients with definite forms of the anemia showed less numer
ous correlations than in controls. The emergence of complications incr
eased the number of persistent correlation pleiads compared to control
s. Moreover, correlation and variance analyses suggested a correlation
between immunity and iron deficiency parameters.
