*NA, not applicable.
†p values are for 2-sided tests of significance of the difference of each coefficient from zero; adjusted p values are according to Holm’s method (10). Percentage changes in the main text can be derived from these coefficients by taking exponentials, subtracting 1, and multiplying by 100.
