Table 4 Changes in the ratio of iodine intake to excretion increment (μg/d)

From: Exploration of the lower threshold of iodine intake in Southern Chinese young adults based on ‘overflow theory’ in an iodine balance study

Variables	period2(△increment)			period3(△increment)
Variables	△increment_in^a	△increment_ex^b	ratio^c	△increment_in^a	△increment_ex^b	ratio^c
Male	12.4	-3.2	-0.324	17.7	29.3	1.675
Female	13.0	9.2	0.699	18.5	19.0	1.034
Total	12.8	4.3	0.293	18.2	22.9	1.276

^a△increment_in was calculated using the iodine intake of latter stage minus the previous stage; △increment_ex was calculated using the iodine excretion of latter stage minus the stage period ; ratio = △increment_ex/△increment_in
