Bars show the percent change in blood flow between body positions for the right lung (white bars) and the left lung (gray bars). Blood flow is greatly increased to the dependent lung compared to non-dependent lung. The P-values placed directly above bars reflect the hypothesis that a given bar has a non-zero value, i.e. that there is a difference in blood flow to a given lung induced by change of body position. The P-values placed above brackets reflect the comparison between the right versus in the left lung
