From: Prognostic impact of hypochromic erythrocytes in patients with pulmonary arterial hypertension
Survival and TTCW according to hypochromic erythrocytes rate. Patients with > 2% of hypochromic erythrocytes showed a shorter time to clinical worsening (TTCW, red lines, left) and had a worse prognosis at baseline (center) and after 1 year follow-up (right) in the univariable and mulitvariable analyses. The displayed p-values correspond to the univariable analysis. Green lines represent patients with ≤ 2% hypochromic erythrocytes
