Fig. 8From: Optimization of training periods for the estimation model of three-dimensional target positions using an external respiratory surrogateBoxplots of the 3D RMSEs for each training period in terms of the modeling session (TM) and baseline drift correction (TC). White triangles: outliers out of range. Black triangles: outliers observed in patient included apnea and hyperpnea data. *p < 0.05Back to article page
