You are right, it was exactly specified in one publication that I2 is more than R1a in Zhytomyr Oblast. I am also trying to obtain that data, I know how this can be done, but a scientist should cooperate. If you ask the publishers Utevska et al. they have the data, they compute MDS analysis of Zhitomir and Chernivtsi, but decline to share it because it is unpublished. There is another way. I know from where the data of Zhytomyr is derived. There are more than 100 samples of Zhytomyr Oblast and more than 100 of Chernivtsi Oblast in the
https://genographic.nationalgeographic.com/for-scientists/ Genographic database from where they are obviously derived by Utevska and her team confirmed by this link.

I suggest he may be interested in looking up for the lacking data of Zhytomyr and Chernivtsi oblast.
