Multiple Logistic Regression for Association Between Placental Malaria and Maternal IgG With CMTRs

	Alexishafen		FIS
	Adjusted Odds Ratio (CI)	P Value	Adjusted Odds Ratio (CI)	P Value
CMTR <0.8
Placental malaria	1.11 (.43–2.87)	.822	0.237 (.024–2.27)	.212
Maternal IgG	2.93 (1.10–7.74)	.03	5.95 (1.32–26.77)	.02
CMTR <1.0
Placental malaria	1.36 (.647–2.87)	.415	0.44 (.099–1.94)	.280
Maternal IgG	2.68 (1.17–6.14)	.020	6.94 (1.94–24.8)	.003

Placental malaria is included in these models as a dichotomous variable, while maternal IgG (measured in mg/dL) is a log₂-transformed continuous measure.

Abbreviations: CI, confidence interval; CMTRs, cord-to-maternal titer ratios; FIS, Fetal Immunity Study; IgG, immunoglobulin G.
