Blood loss based on age and the presence of cyanotic disease. *p < 0.005 comparing < 1 month and 1-6 months with cyanotic disease (mean difference between groups 7.9% estimated blood volume (EBV), 95% CI 1.4 to 14); ** p < 0.05 comparing 1-6 months and 6-12 months with cyanotic disease (mean difference between groups -6.1% EBV, 95% CI -12 to -0.15); *** p < 0.05 comparing 1-6 months and 1-3 years with cyanotic disease (mean difference between groups -5.6% EBV, 95% CI -11 to -0.12); **** p < 0.005 comparing 1-6 months and > 3 years with cyanotic disease (mean difference between groups -6.9% EBV, 95% CI -13 to -1.3).
