CT signs and pejorative evolution
Associations between COVID-19 typical CT signs and intensive care unit
hospitalization, use of invasive endotracheal ventilation and death are
summarized in Table 3, with the calculated p-values, only for the 109
RT-PCR positive patients.
Bronchial distortion was significatively associated with mortality (p =
0,018), ICUH and invasive endotracheal ventilation (p <
10-3). Vascular
dilatation and a number of involved lobes ≥ 4 were significatively
associated with invasive endotracheal ventilation and ICU
hospitalization (p < 10-3). Total lung
volume involvement ≥ 50 % was also significatively associated with
death, invasive endotracheal ventilation and ICUH (p <
10-3). Air bubble sign (p = 0,039), interlobular (p =
0,026) and peribronchovascular thickening (p = 6.10-3)
were associated with invasive endotracheal ventilation.
