Box-plot (outliers, minimum, lower quartile, median, upper quartile and maximum) of the maximum confidence level at which the effect of the different categories of the variable on the total number of contacts becomes significantly different. The dispersion of the box plot refers to the variation of this value over different age groups. Results are shown for education level, employment situation, income level (which is present from the 2nd W, since this information was missing in the first few data collections), gender, settlement, chronic disease, acute disease, and smoking behaviour. The higher this value is, the more the variable influences people’s number of contacts given their age. The horizontal dotted line is placed at 95% and it represents the confidence level at which the AME is considered to be statistically significant. Sample sizes are indicated in Section 1.2. of SI.
