Survival analysis in clustered complications, nomogram building, and validation.
COMPLICATION, SCHISTOSOMIASIS, COMPLICATIONS
The survival curves of each cluster (clustered complications) were plotted. We established a nomogram based on the clustered complications from the network analysis to predict the overall 5-year survival rate in advanced schistosomiasis. A certain cluster (stored as a binary variable) was labeled as positive if any isolated complication within this cluster presented. All the clusters, along with the age of the training cohort, were integrated into a nomogram to predict the survival rate of individual patients with advanced schistosomiasis. Calibration curves were used to evaluate the prediction ability of the nomogram, which was also validated.
