Age distribution as a function of the level of severity determined by the NACA score. Boxplot 1 represents all the missions in 2018 (n = 35,156, 32 data items missing). Boxplots 2 and 3 respectively represent the age distributions for the prehospital missions with NACA scores between 0 and 3 (non-urgent, n = 30,633) and NACA scores between 4 and 7 (vital emergency, n = 4523). The Mann–Whitney U test shows that the two medians are different with high significance. For NACA scores 0–3 and NACA scores 4–7, statistical values are respectively: median: 64–69, SD: 26.06–22.80, IQR: 45–30
