highly significantp < 0.001
Between t0 and t2, there was a highly significant increase in leukocytes in the COVID group (t0: m = 5.50 [± 1.75] 10 ˄ 3/μl; t2: m = 7.38 [± 2.4] 10 ˄ 3/μl; t(29) = −7.426, p < 0.001), and the increase in leukocytes between t0 and t1 (t1: m = 6.73 [± 2.34] 10 ˄ 3/μl; t(30) = −4.204, p < 0.001) and t1 and t2 was also significant (t(29) = −2.948, p = 0.019).
