Most importantly, no statistically significant difference in the risk of delivering a low birth weight infant was observed for adolescent mothers in multivariable analysis after correction for the number of antenatal care visits.
The study did not start until the infant was observed to be sucking at the breast.
Each infant was observed for 30 minutes after the injection for any immediate vaccine related reactions.
One researcher visited the NICUs and observed each infant for 3 12 hours over the course of 1 3 days (more than one infant was observed at a time).
The corneal mass in this infant was observed immediately after birth; its initial presentation was a pink raised uplifted neoplasm in the central cornea, which was similar to a corneal dermoid.
A comprehensive decision-model based on analysis of a Canadian population-based Canadian administrative data source suggested that substantial costs per infant are observed in early and moderate preterm infants, but when scaled to the national level, late preterm infants contribute a substantial burden due to the relatively larger population size.
Counting the number of serotypes each infant was observed to have carried at one or more time points gives a distribution that is considerably, and highly significantly, under-dispersed relative to simulations under the assumption of independent assortment of serotypes would lead us to expect.
Intervention food preparation and consumption by the infant are observed during home visits by the research staff on a daily basis for the first two weeks of the intervention; 3 times per week for the first 3 months; and then weekly for the remainder of the intervention.
Fifteen infants were observed at home before, during, and after learning to crawl in two naturalistic contexts, free play and dyadic play.
Utilizing a double-blind, placebo-controlled, within-subject design, 35 fathers and their 5-month-old infants were observed in a face-to-face-still-face paradigm twice, one week apart.
