To develop and internally validate a nomogram incorporating red blood cell and reticulocyte indices to differentiate thalassemia trait from iron deficiency anemia.
Analyzed a retrospective cohort of 517 patients (320 with iron deficiency anemia, 197 with thalassemia trait) randomly partitioned into training (n = 361) and validation (n = 156) sets using 7:3 stratified sampling.
Evaluated red blood cell parameters (RBC count, MCV, MCH) and reticulocyte indices (RET%, IRF, LFR, MFR, HFR) using LASSO and multivariate logistic regression, testing performance via ROC curves, calibration plots, and decision curve analysis.
Multivariate analysis identified four independent predictors: elevated RBC count associated with thalassemia trait (p < 0.001), while higher MCV, RET%, and HFR associated with iron deficiency anemia (all p < 0.001).
The nomogram achieved an AUC of 0.900 in the training cohort and 0.904 in the validation cohort, demonstrating good calibration and net clinical benefit across threshold probabilities of 7%–96% and 5%–97%, respectively.
