Linear and quadratic associations between AAM and indices derived from the OGTT (and related variables)

OGTT-related variable	n	Linear regression		Mixed linear/quadratic regression
				Linear term		Quadratic term
		β	p value	β	p value	β	p value
Pre-pregnancy BMI	658	−0.180	3.3 × 10−6	0.378	0.5	−0.560	0.3
Maternal height	690	0.209	3.2 × 10−8	0.442	0.4	−0.234	0.6
HOMA IR	731	−0.128	5.2 × 10−4	−0.925	0.05	0.799	0.09
HOMA B	731	−0.110	2.8 × 10−3	−0.499	0.3	0.390	0.4
OGTT 60 min glucose	723	−0.096	0.01	−0.129	0.8	0.034	0.9
Capillary glucose AUC	619	−0.068	0.09	−0.503	0.3	0.436	0.4
C-peptidogenic index	684	−0.002	1.0	−0.669	0.2	0.669	0.2
C-peptide disposition index	684	0.065	0.09	−0.170	0.7	0.235	0.6

In each case the analysis was restricted to those samples where full C-peptide-derived HOMA data were available
