GA, gestational age; LBW, low birth weight
Bold values represent statistically significant ORs
a
low birth weight is defined as weighing less than 2500 grams at birth
b
conditional probability of exposure to fever modeled as a function of child sex, maternal age, birth year, maternal smoking, education, marital status, race, gestational age
