Fig. 3From: Development and validation of a nomogram to predict plastic bronchitis in children with refractory Mycoplasma pneumoniae pneumoniaNomogram to predict PB among RMPP children was constructed based on 6 independent predictors. Mark the value of these included factors on the corresponding axis. Draw a vertical line from the value to the top lines and get corresponding points. Then, sum the points from each variable value. Locate the sum on the total points scale and project it vertically on the bottom axis to obtain a PB riskBack to article page
