Figure 1From: Predicting outcomes after blunt chest wall trauma: development and external validation of a new prognostic modelCalibration of model using expected and observed probabilities of development of complications. Triangles show risk of outcome in tenths of patients with similar predicted probabilities. Dotted line: relationship between observed frequency and predicted probability of development of complications; broken line: ideal relationship between observed and predicted frequency of outcome in model with perfect calibration.Back to article page
