In addition, compared with high‐dose methylprednisolone sodium succinate (MPSS) treatment, intravenous administration of G‐CSF produced significantly higher ASIA motor scores.243 Furthermore, less severe side effects such as pneumonia were observed in patients treated with G‐CSF, indicating that intravenous administration of G‐CSF is safer and more effective. Here, CSF3 is linked to susceptibility to pneumonia measurement.
