In the
pneumonia
associated with SARS-CoV-2 group (n = 127), we found that the GGO ratio
was correlated with
FiO2,
PaO2/FiO2 ratio
(r= 0.59, -0.58; p <0.01, respectively). Although the
consolidation ratio associated with FiO2,
PaO2/FiO2 ratio (r = 0.32, -0.39;p <0.01, respectively), the strength of correlation was
weaker when compared with GGO.
Multiple
linear regression result indicated that GGO ratio was associated with
PaO2/FiO2(ß= -3.0, p <0.01; R2 = 0.4,p for model <0.01 ) when adjusted
with consolidation ratio
(ß= -0.85, p =0.25 ), Age (ß = -0.98, p =0.08 ), Gender
(ß = 4.10, p =0.73 ), hemoglobin
level
(ß = 0.15, p =0.54 ), and D-Dimer level (ß = 0.03,p =0.58 ); while the consolidation ratio was correlated with
PaCO2 level (ß = 0.43, p <0.01;R2 = 0.28, p for
model<0.01 )
when adjusted with GGO ratio (ß = -0.1, p =0.98 ), Age
(ß = -0.037, p =0.57 ), Gender (ß = -3.5, p
=0.01 ), hemoglobin level (ß = 0.008, p =0.77 ), and
D-Dimer level (ß = -0.001, p =0.80 ). Additionally, the
consolidation ratio (ß = 0.692, p<0.01 )) also
associated with neutrophil–lymphocyte ratio (NLR) when adjusted with
GGO ratio (ß = 0.003, p =0.99 ) (The results of multiple
linear regression were demonstrated in Fig.4.)
