Fig. 1From: Is the urinary iodine/creatinine ratio applicable to assess short term individual iodine status in Chinese adults? Comparison of iodine estimates from 24-h urine and timed-spot urine samples in different periods of the dayDifference between measured and estimated urinary iodine excretion in different periods of the day. UIE, urine iodine excretion; mUIC, median urinary iodine concentration; *Estimated urinary iodine excretion was significantly different compared to the measured urinary iodine excretion (P < 0.05) by Spearman rank correlation analysis; **Estimated urinary iodine excretion was significantly different compared to the measured urinary iodine excretion (P < 0.01) by Spearman rank correlation analysis; ***Estimated urinary iodine excretion was significantly different compared to the measured urinary iodine excretion (P < 0.001) by Spearman rank correlation analysisBack to article page
