The paper makes a lot of models but the analysis is mostly handwaving. They don't do a statistical significance test.

However, the difficulty of quantitatively assessing the statistical significance of the above findings must be emphasized. This is because of the absence of observational errors for the various offsets derived from Fig. 6 of Kim et al. (2021).
