Fig. 4From: The roles of lumbar load thresholds in cumulative lifting exposure to predict disk protrusion in an Asian populationReceiver-operating characteristic curves for the prediction of L4-S1disc protrusion in female participants by models of different threshold of lifting load. Model 0: AUC (95% CI) = 0.60 (0.54Â -Â 0.65). P = 0.0154. Model 2800: AUC (95% CI) = 0.62 (0.56Â -Â 0.67). P = 0.0031. Model 3400: AUC (95% CI) = 0.59 (0.54Â -Â 0.65). P = 0.0159Back to article page
