Six-year OS rate in patients with SAA treated with ATG/CSA with or without G-CSF. Six-year OS rate in patients with SAA treated with ATG/CSA with or without G-CSF. (A) OS of all 192 patients; (B) OS according to disease severity, comparing patients with SAA (blue), and very SAA (green); (C) OS according to age groups: patients < 20 years (blue), patients aged 20-40 years (green), patients aged 40-60 years (red), and patients aged > 60 years (lilac).

Evolution of neutrophil counts during the first year in patients treated with ATG and CSA with and without G-CSF. Evolution of neutrophil counts during the first year in patients treated with ATG and CSA with and without G-CSF. The bold red line represents the median, and the yellow surface represents the 75% CI of the neutrophil counts in patients treated with G-CSF; the bold blue line represents the median, and the blue surface represents the 75% CI of the neutrophil counts in patients treated without G-CSF; the gray surface represents the overlapping surface of 75% CI of patients treated with and without G-CSF.

Survival of patients randomly assigned to receive G-CSF with neutrophil counts ≥ 0.50 × 109/L (blue) at day 30 compared with patients with neutrophil counts < 0.50 × 109/L (green).
