†
Pearson’s correlation coefficients between egg consumption and the row variables.
‡
Percentage change in values of egg consumption per 1 sd increase in the row variable (or for categorical variables, the percentage difference in mean values of egg consumption for the category v. the reference); asterisks indicate the level of statistical significance: *P < 0·05; ***P < 0·001.
