mJOA score and RR of patients in each cluster. The mJOA scores of patients in each cluster were improved postoperatively. (A) The recovery ratio of mJOA score (mJOA RR) was used to evaluate the prognosis of patients in each cluster. (B) The mJOA RR of patients in cluster 2 and 4 were more than 50%, indicating a good prognosis, while those in cluster 1 and 3 had a poor prognosis.
