Number and diameter of the different lipoprotein particles in patients with lung cancer (LC) (A), head and neck cancer (HNC) (B) before and after radiotherapy (RT) and in the control group. Values are log transformed due to the high variability of particle sizes and numbers. Results are shown as means and standard errors. HDL: high-density lipoproteins; IDL: intermediate-density lipoproteins; LDL: low-density lipoproteins; VLDL: very-low-density lipoproteins. The suffix −P indicates number of particles, and the suffix −Z indicates the particle diameter. a

p < 0.01, c
p < 0.001, with respect to the control group by the Mann-Whitney U-test.
