Reproducibility of Bioelectrical Impedance Analysis in Pregnancy and the Association of Body Composition with the Risk of Gestational Diabetes: A Substudy of MUMS Cohort

Table 4

Reproducibility in the method comparison of Bodystat vs. RJL for measurement of impedance (Ω).

	ICC^a	ICC 95% CI	Average difference^b	LOA	value^c
Bodystat vs. RJL
T1	0.966	0.951–0.976	0.71	−9.83, 11.25	0.16
T2	0.994	0.991–0.996	2.14	−14.62, 18.90	0.01
T3	0.966	0.950–0.977	4.16	−18.54, 26.86	<0.001

^a value for ICC all <0.001. ^bDifferences calculated as Bodystat minus RJL. ^c value for paired t-test of differences between instruments. CI: confidence interval; ICC: intraclass correlation coefficient; LOA: limits of agreement; and T1/2/3: trimester 1/2/3.
