The nomogram composed of eight variables predicting the probability of survival time less than the median follow-up time (13.5 months). For a given sample, each variable had a point, and the total point reflected the final probability. The blue bars and bean charts represented the distribution of patients corresponding to the different characteristics. Asterisks represented the statistical results of multivariate COX regression, with * indicating p < 0.05, ** indicating p < 0.01, and *** indicating p < 0.001
