This statement is wrong on multiple levels, I can't believe Nature would not catch that in the abstract.

  1. They don't clarify if they are referencing statistical significance;
  2. It is not significant at p = 0.07
  3. It is likely not even near significant if they accounted for multiple comparisons (p-hacking).
  4. Under the hypothesis test framework, things can't be marginally significant. It is either significant or it isn't.
