Serologic Variable	Transfer Ratio,^a Median (Range)		P Value^c
Serologic Variable	Monotypic^b	Multitypic^b	P Value^c
DENV-specific IgG	103.9 (68.4–141.9)	101.7 (75.3–137.7)	.02
DENV-3 neutralizing Ab	106.8 (39.5–192.5)	104.3 (72.1–146.5)	.04
DENV-specific subclass
IgG1	103.5 (76.0–175.4)	103.1 (73.8–137.3)	.36
IgG4	98.0 (56.9–161.0)	95.1 (60.0–127.6)	.16

Abbreviation: IgG, immunoglobulin G.

^a Calculated as follows: [newborn antibody titer/maternal antibody titer] x 100.

^b Determined by a plaque reduction neutralization test.

^c By the Mann–Whitney test.
