highly significantP value = 8.8*10 −16
A highly significant positive correlation ( r = 0.74, P value = 8.8*10 −16 at 95%, CI = [0.62,0.82]) of BC with infection counts and with Death considering 10 days lag ( r = 0.84, P value = 2.02*10 −13 at 95%, CI = [0.73,0.91]) for the entire period, supports the above interpretation ( Fig. 2 (a, b)).
