Table 3.
Median (range) haptoglobin levels, stratified by group and time point.
| Variable | Groups | Time point | P-value | ||
|---|---|---|---|---|---|
| M1 (pre-CPB) | M2 (post-CPB) | M3 (24h PO) | |||
| Haptoglobin (mg/dL) | G1 (roller pump) | 101.45 (20.90-231.60)B | 9.30 (0.00-161.00)A | 38.90 (0.00-133.80)A | < 0.05 |
| G2 (centrifugal pump) | 85.50 (0.00-263.90)B | 17.70 (0.00-248.00)A | 32.30 (0.00-158.30)A | < 0.05 | |
| G1 × G2 | P-value | P>0.05 | P>0.05 | P>0.05 | |
CPB=cardiopulmonary bypass; PO=postoperatively. Uppercase letters denote within-group comparisons between time points.
A
denotes the lowest value measured, and Bthe highest value measured.
B
the highest value measured.
