Nomogram for predicting the risk of sepsis in children with Staphylococcus aureus bloodstream infections (a). The children’s score for each risk predictor is plotted on the appropriate scale. A total score was calculated by adding each single score. The total points score is plotted on the bottom total points scale. The corresponding value shows the predicted probability of incident sepsis in children with Staphylococcus aureus bloodstream infections. The histogram showed the sepsis number in each group. Underlying diseases: none = 0, congenital heart disease = 1, gastrointestinal malformations = 2, tumor = 3, funnel chest or congenital diaphragmatic hernia = 4. HR, hazard ratio; PCT, procalcitonin
