Figure 2From: Are standard doses of piperacillin sufficient for critically ill patients with augmented creatinine clearance? Piperacillin drug clearance compared with creatinine clearance. Scatter plot of piperacillin clearance (CL) and creatinine clearance (CLCR). A linear regression line (solid) with 95% confidence interval (dashed line) has been fitted to the data points (r = 0.58, P < 0.001).Back to article page
