Fetal heart groups determined by GBTM

FHR group	Posterior probability	GA at birth	BWP
1 (n = 28)	0.987 ± 0.040	39.47 ± 1.16	50.11 ± 24.76
2 (n = 23)	0.992 ± 0.037	39.36 ± 1.06	34.65 ± 21.33^a
3 (n = 38)	0.983 ± 0.039	39.42 ± 1.65	53.0 ± 29.42
4 (n = 39)	0.987 ± 0.049	39.03 ± 1.37	60.13 ± 25.10^a
5 (n = 28)	0.998 ± 0.006	39.48 ± 1.21	42.25 ± 26.83

GBTM, group-based trajectory modeling; FHR, fetal heart rate; GA, gestational age; BWP, birth weight percentile.

Average probability of group membership, GA and BWP for each group.

All values are given as (mean ± s.d.).

FHR groups 2 and 4 significantly differ in BWP; Bonferroni post hoc comparisons with parity and estimated fetal weight at time of assessment as covariates, P = 0.01
