Comparison of the contributions of the middle and inner adipose layers (L2 and L3, respectively) to the total adipose thickness at each scan time

Adipose layer	Scan	Estimate change	Lower CI (95%)	Upper CI (95%)	P
L2	1 vs 2	-0.07	-0.23	-0.004	0.014
	1 vs 3	-0.10	-0.27	-0.33	0.006
	2 vs 3	-0.002	-0.03	0.29	0.45
L3	1 vs 2	0.68	0.55	0.81	<0.001
	1 vs 3	0.70	0.76	0.84	<0.001
	2 vs 3	0.0002	-0.03	0.004	0.49

Test statistics are based on data from the linear regression model. "Estimate change" is the square of the alteration in the ratio of layer thickness to total adipose thickness between scans, estimated by the model. The later value is subtracted from the earlier value, so an increase in proportion is indicated by a minus sign. Ratios were transformed prior to fitting in the model; the statistical output for these ratios has been back transformed for this table."CI" indicates confidence interval." P" is the probability (with 12 degrees of freedom) that the difference between the transformed ratios at each scan is equal to zero.
