In addition, a distinction was made between different significance levels: in the Results Section (see Section 3 ), a p -value of p ≥ 0.05 corresponded to “non-significant” (n.s.), p < 0.05 to “significant” (*), p < 0.01 to “highly significant” (**) and p < 0.001 to “very highly significant” (***).
