In order to determine the within-subject variability of creatinine excretion, the 24-h output was measured over 5 consecutive d in 12 subjects. The mean within-subject coefficient of variation was 3.6 per cent. There was much greater variation between subjects. The creatinine excretion in g/d was 30-40 per cent lower in Burmese subjects than in Europeans and North Americans, but the excretion per kg was slightly higher, suggesting that the Burmese are more muscular.
为了确定肌酐排泄的个体内变异性，对12名受试者连续5天测量其24小时排出量。个体内变异系数的平均值为3.6%。个体间的变异则大得多。缅甸受试者的肌酐排泄量（克/天）比欧洲人和北美人低30% - 40%，但每千克体重的排泄量略高，这表明缅甸人肌肉更发达。
