Nomogram-based prediction of post-splenectomy thrombocytosis in children with hereditary spherocytosis

Table 4 Discriminatory ability of predictors (receiver operating characteristic analysis)

Predictors	AUC	95%CI	P value
Reticulocyte (%)	0.79	0.73-0.85	< 0.001
Preoperative platelet count	0.76	0.69-0.83	0.002
Transfusion volume	0.78	0.72-0.84	0.001
MPV	0.73	0.66-0.80	0.004
Combined model	0.92	0.87-0.96	< 0.001

Receiver operating characteristic curve analysis was performed to evaluate the predictive ability of individual parameters and the combined model. AUC: Area under the curve; CI: Confidence interval; MPV: Mean platelet volume.
