A decision curve plot showing standardized net benefit (y-axis) against threshold probability with corresponding cost–benefit ratios (x-axis). The thick red line represents standardized net benefits of the nomogram across probability thresholds and the accompanying two thin red lines represent the 95% confidence interval; the grey line with its 95% confidence interval represents standardized net benefit of treating all preterm septic neonates in the same way regardless of their mortality risk; the black line represents standardized net benefit of treating none of the preterm septic neonates which is zero
