The decision curve analysis of the nomogram

Decision curve analysis for the nomogram. Notes: the y-axis measures the net benefit. The red line represents the IR risk nomogram. The blue line represents the assumption that all patients are IR. The green line represents the assumption that no patients was considered to exhibit IR. The decision curve showed that if the threshold probability of a patient was above 12%, using this IR nomogram in the current study to predict insulin resistance risk adds more benefit than all-interventionor the none-intervention.
