Complications and Chest CT Manifestations
Five studies reported that
a
small number of patients
developed
shock. Estimates of the proportion of patients developing shock were
0.03 (95% CI 0.01, 0.07) (I2=81%, p<0.01).
Data from 6 studies that reported information on ARDS was pooled. The
results revealed that the proportion of patients developed ARDS was 0.11
(95% CI 0.05, 0.22) (I2=92%, p<0.01).
There were five or three studies offering data of patients developing
acute kidney injury (AKI) or acute cardiac injury, respectively. The
pooled results showed that the proportions of patients developing AKI or
acute cardiac injury were 0.02 (95% CI 0.01, 0.04)
(I2=55%,p=0.04) or 0.05 (95% CI 0.01, 0.17)
(I2=72%, p=0.61), respectively (Fig.4A,B,C,and D).
Eight studies provided information on chest x-ray or CT findings. The
pooled results revealed that the proportion of patients with bilateral
pneumonia was 0.79 (95% CI 0.69, 0.87) (I2=92%,
p<0.01), unilateral pneumonia was 0.11 (95% CI 0.04, 0.27)
(I2=97%, p<0.01) (eFigure 2 in the
Supplement).
