Results
The proportion of HbSS phenotype was similar in the group with
FEV1% predicted ≥ 65 and the group with
FEV1% predicted < 65, as was the proportion
of HbSC phenotype (Table 1). Additionally, maternal parity was similar
in the two FEV1% predicted groups. Moreover, the two
FEV1% predicted groups were similar with respect to the
mean maternal ages, gestational ages, maternal BMI, and hemoglobin
concentrations. The mean FVC % predicted and FEV1/FVC
% predicted were higher in the FEV1% predicted ≥ 65
group compared with the FEV1% predicted < 65
group.
