1. a The FPC1 scores in model 1 and the AUC in model 4 yielded nearly identical results and the AUC results are thus not shown.
2. b p values from pairwise comparison between adjacent groups.
3. c n=711. Calculated as 2-h value minus 90-min value, or 90-min minus 60-min value [12].
4. * Categories of 2-h values in the third trimester is the response variable and OGTT characteristics in gestational weeks 14–16 are explanatory variables. All models are adjusted for BMI in gestational weeks 14–16.
