Pearson correlation (R) between the international trade (the sum of total amount of import and export) and hospitalized patients in Intensive Care Units (ICU) in France, Italy, and Spain regions.

	ICU occupancy first wave		ICU occupancy second wave
	R (95% CI)	p-value (2 sided)	R (95% CI)	p-value (2 sided)
International trade Italy	0.967 (0.917–0.987)*	3.60E-12*	0.943 (0.859–0.978)*	4.93E-10*

International trade Spain	0.957 (0.890–0.984)***	1.42E-10***	0.920 (0.799–0.969)***	2.60E-08***

Population density France	0.945 (0.821–0.984)**	1.16E-06**	0.778 (0.398–0.930)**	1.72E-03**

Note: The correlation is reported also between the density of population and ICU occupancy for all the regions. First wave ICU data refer to 13^th April for France** and Spain*** and to 1^st April for Italy*. Second wave ICU data refer to 13^th November for France**, 6^th November for Spain*** and to 18^th November for Italy*.
