From: Kinesiophobia is not required to predict chronic low back pain in workers: a decision curve analysis
Decision curves of the prediction Models 1 and 2 to predict chronic LBP. Y-axis is Net Benefit and x-axis is threshold probability pt. Dotted black line belongs to the Net Benefit of prediction Model 1, dotted grey line to Model 2. The black line is the Net Benefit when all patients are assumed negative and the grey line is the Net Benefit when everybody is assumed positive and would be treated. * The Net Benefit of the model around 90% is sometimes negative due to random noise [9]
