  1. Effect size was standardised by two SD. Parameters with a significant effect (p < 0.05) are highlighted in bold.
  2. aWind 0 was the reference category.
  3. bUnstandardised partial slope values obtained after model fit with the same fixed and random effects, but without standardization of the input variables.
