Coronal plane joint moments for the 20 patients. The circles represent outliers (those data points between 1.5 and 3.0 times the interquartile range outside the first and third quartiles respectively) and the asterisks represent extreme outliers (more than 3.0 times the interquartile range outside the first/third respectively). The scale shows joint moments in Nm and + ve is a clockwise moment. Patient 5 is shown in orange, Patient 13 is shown in green and Patient 14 is shown in blue
