	Birth Weight Centile		SGA < 5th Centile			SGA < 10th Centile
	Mean ± Std	P	N (%)	RR (95% CI)	P	N (%)	RR (95% CI)	P
NNN	50.5 ± 27.9	N/A	3 (2.3)	1.0 (referent)	N/A	9 (6.9)	1.0 (referent)	N/A
H	54.9 ± 26.1	.47	1 (4.0)	1.7 (0.2-16.1)	.62	1 (4.0)	0.6 (0.1-4.4)	.60
U	50.3 ± 27.6	.96	1 (3.0)	1.3 (0.1-12.3)	.81	1 (3.0)	0.4 (0.1-3.4)	.43
HP	60.4 ± 28.2	.07	1 (2.9)	1.3 (0.1-12.0)	.83	2 (5.9)	0.9 (0.2-3.8)	.84

HPU	33.6 ± 20.2	.022	1 (6.3)	2.7 (0.3-24.7)	.37	2 (12.5)	1.8 (0.4-7.7)	.42

Abbreviations: NNN, normal blood pressure, urinary protein, and uric acid; H, hypertension; U, hyperuricemia; HP, hypertension and proteinuria; HU, hypertension and hyperuricemia; HPU, hypertension, proteinuria, and hyperuricemia; Std, standard deviation; SGA, small for gestational age; RR, relative risk; CI, confidence interval.

^aOther contrasts of interest for birth weight centile are as follows: HU versus H (P = .32), HU versus HP (P = .09), and HPU versus HP (P < .01). Other contrasts of interest for SGA < 5th centile are as follows: RR (95% CI), P value]: HPU versus HP [2.1 (0.1-31.9), P = .59), HU vs HP [6.4 (0.7-56.6), P = .10], HU vs H [4.7 (0.5-41.2), 0.16]. Other contrasts of interest for SGA < 10th centile are as follows (RR [95% CI], P value): HPU versus HP (2.1 [0.3-13.8], P = .43), HU versus HP (3.2 [0.6-17.2], P = .18), and HU versus H (4.7 [0.5-41.2], P = .16).
