The adjusted correlation between the number of days in which environmental pollutants exceeded established limits and the overall number of COVID-19 cases as recorded by the Italian Ministry of Health is shown in Figure 1a , which reveals the existence of a highly significant positive association (r=0.66; 95% CI, 0.48-0.79; p<0.001).	./cache/cord-293838-avri3xuc.txt	./txt/cord-293838-avri3xuc.txt
