  1. 1 The n is unweighted. The sample size may vary for some variables, because of missing values. Means and standard deviations (SD) and p-values for country-differences tested with ANOVA are presented for normally distributed continuous variables. Medians and Interquartile ranges (IQR) and p-values for country-differences tested with Kruskal-Wallis test are presented for skewed continuous variables. Percentages and p-values for country-differences tested with the Chi-squared were presented for categorical variables.
