FIG 2.

(A) Median hemoglobin (Hb) concentration at days 0, 14, and 28 (n = 224 patients with ACPR); (B) relative Hb change (between day 0 and day 14) according to baseline Hb values (cutoff for anemia, Hb concentration of <11.0 g/dl) (n = 240). Relative Hb change on day 14 (%) by linear regression: (i) anemia group, coefficient β = −10.00; 95% CI, −12.81 to −7.19; P < 0.001; (ii) nonanemia group, β = −6.46; 95% CI, −7.41 to −5.51; P < 0.001. A significant interaction was found between Hb change at day 14 and anemia status at day 0 (interaction term β = −5.99; 95% CI, −8.87 to −3.11; P < 0.001).
