Predict the identified clusters in the patients with BSI. (A) Nomogram to predict the identified clusters. Points are assigned based on 4 baseline variable by drawing a line upward from the corresponding values to the “Points” line. The sum of these four points, plotted on the “Total points” line, corresponds to possibility of cluster 2. The bloodstream infections clustering (BSIC) score derives from the nomogram, allows the user to partition patients into 2 clusters by calculate total point. (B) Calibration plot of BSIC score. The proportion of patients attributed to cluster 2 increased with the score. (C) Receiver operating characteristic curves (ROC) for discrimination estimate. Abbreviation: DVC, Deep vein catheterization; MV, mechanical ventilation; BSI, bloodstream infection; AUC, area under the curve
