Cerebral palsy (CP) was studied in 182 MC infants and 189 DC infants matched for weight and age at delivery, gender, ethnicity of the mother and study center.
With this in mind, the aim of our study was to compare lung volume, ventilation inhomogeneity and tidal breathing parameters in preterm infants with and without BPD with term-born infants matched for post-conceptional age at study date.
25 infants were included in the ECF group and 50 control infants matched for gestational age were included in the DRI group.
Study design The sample included 477 exposed and 554 comparison infants matched for race, sex, and gestational age.
Results: There were 68 cases with cerebral palsy and 157 controls (singleton term infants matched for gestational age and hospital of birth).
To compare the pulmonary clinical course and outcome of very preterm infants (gestational age 25 32 weeks) with respiratory distress syndrome (RDS) who started with ENCPAP and failed (ECF group), with a control group of infants matched for gestational age, who were directly intubated in the delivery room (DRI group).
We were careful to select the happy, neutral and sad faces of 13 infants and 13 adults such that the stimuli were matched for emotional valence and arousal (infants: 0.2 (1.9), mean (standard deviation) and adults: −0.1(2.1), not significant) across the two groups.
All face images used in the imaging task were presented as grayscale images, with adult and infant faces matched for emotional expression, as well as size and luminosity to minimize possible confounding effects of visual appearance.
In contrast, at 2 years' postpartum, Moses et al. (20) compared the fasting metabolic profile of 18 women with LGA infants against that of 18 women with appropriate-for-gestational-age infants, carefully matched for maternal age, BMI, parity, and 2-h glucose level on the antepartum OGTT.
Control infants were matched for year of birth, gestational age, and birth weight.
