Figure 1From: Are standard doses of piperacillin sufficient for critically ill patients with augmented creatinine clearance? Piperacillin concentrations over time grouped according to creatinine clearance quartile. Mean piperacillin concentration (log10 scale) and time grouped according to creatinine clearance (CLCR) quartile: <68 ml/min (black diamonds), 68 to 114 ml/min (grey diamonds), 115 to 170 ml/min (black squares) and >170 ml/min (grey squares). The dotted line at 16 mg/L represents minimum inhibitory concentration.Back to article page
