Renal filtration and perfusion responses in the SWL-treated kidney. Individual responses are shown with black lines, and the mean and Standard Error of the Mean (SEM) value of the group response are shown in red. GFR = glomerular filtration rate, RPF = effective renal plasma flow, Basal = baseline value, pSWL = 1 h post-treatment (sham or SWL) value, * = P<0.05 from baseline value.
