a The correlation between LUSI and CTSI. Legend: the shaded area is a Bland–Altman where the line represents the biased association between the measurements (lung ultrasound underestimates CT involvement) and the shaded area represents the limits of agreement. The measurement error decreases with increased involvement. LUSI lung ultrasound score severity index; CTSI computed tomography severity involvement index. b Concordance between changes in sequentially measured LUSI and changes in CTSI. Legend: green squares denote concordance (involvement changes in the same direction) and red squares represent discordance (involvement changes in different directions). LUSI lung ultrasound score severity index; CTSI computed tomography severity involvement index
