Correction

After publication of this work [1] it was noticed three author names were spelt incorrectly. Liudmila Iashyna should be Liudmyla Iashyna, Marina Polyanskaya should be Maryna Polianska and Elcan Mamamdbayov should be Eljan Mammadbayov.

In Table 2 in the first row of the column ‘Centre’ the name ‘National Medical University named after A.A. Bogomoltz’ should be changed to: ‘National Medical University named after O.O. Bogomolets’.

The original article was corrected.

The publisher apologises for this error.
