Cranial drift of the diaphragm dome during PIBH and PEBH. The diaphragm drift velocity during PIBH and PEBH A over all volunteers per session and B per volunteer and session are depicted, showing that the drift velocity is smaller during PIBH than during PEBH. Boxes: median value and lower and higher quartiles, whiskers: lowest and highest data point within 1.5 times the inter-quartile range (IQR), dots outside the whiskers: outliers, data points outside 3 times the IQR, ‘x’ denotes the mean value
