Figure 3 Changes in SCr concentration (baseline to peak) after contrast administration for coronary angiography. Baseline and peak SCr concentrations within 48 h after contrast administration are shown for each patient in the iodixanol (n = 140) and ioxaglate (n = 135) study arms. The vertical lines and symbols illustrate the mean (± SD) baseline and peak SCr values for the 2 groups as described in the text; p values refer to the difference between baseline and peak SCr for iodixanol and ioxaglate, respectively. See text for additional details. To convert values for creatinine to micromoles per liter, multiply by 88.4. mOsm/kg = milliosmoles per 1,000 grams; mPa·s = millipascal seconds; SCr = serum creatinine; SD = standard deviation.
