Figure 2 Trends in hemoglobin, lactate dehydrogenase, and haptoglobin following presentation. Hemoglobin levels (g/dL) are displayed on the left Y-axis, and lactate dehydrogenase (U/L) and haptoglobin (mg/dL) on the right Y-axis, plotted against time since presentation (days) on the X-axis. Hemoglobin is shown as a solid line with circular markers, lactate dehydrogenase as a dashed line with triangular markers, and haptoglobin as a dashed line with diamond markers. Haptoglobin values below the assay detection limit are displayed as zero for graphical representation. Small symbols positioned above the X-axis indicate therapeutic interventions: a triangle denotes initiation of prednisone on day 1, and diamonds indicate rituximab doses administered on days 5, 14, 21, and 28.
