Study design: Growth-restricted and non-growth-restricted children were identified at age 9 to 24 months, at which time the growth-restricted children participated in a 2-year randomized trial of nutritional supplementation and psychosocial stimulation.
Study design: The Growth and Health Study recruited 9- and 10-year-old girls from Richmond, California, Cincinnati, Ohio, and Washington, DC.
Study design: The growth of the cells was studied after in vitro or dietary supplementation with Se in a murine model.
Study Design: Placenta growth factor concentrations were measured in the tissue homogenates of 12 normal placentas, 33 complete hydatidiform moles, and 6 gestational choriocarcinomas.
Study Design: Intrauterine growth restriction was induced in 7 fetal sheep from 120 to 140 days' gestation (term, approximately 147 days' gestation) by umbilicoplacental embolization.
Study design: Hepatocyte growth factor levels were measured in 42 plasma samples between weeks 14 and 21 of gestation using an enzyme-linked immunosorbent assay (ELISA).
Study design: Individual growth curves of systolic BP (SBP) and diastolic BP DBPP) were created for 745 black and white male and female youths, with annual assessments over a 10-year period (age range, 4.9-27.5 years).
Study Design: Insulin-like growth factor and insulin-like growth factor binding proteins were measured by immunoradiometric assay and Western ligand blotting in sera from 39 postmenopausal women treated with sequential hormone replacement therapy for 1 year.
Study design: We evaluated growth status, phenotype, and ovarian function in 7 girls with 45,X/47,XXX mosaicism, age-matching each with 2 girls with 45,X and 1 with 45,X/46,Xi(X)(q10) karyotypes.
The similarities with regard to study design and the growth factor used make comparison of the studies feasible.
Study Design: Serum vascular endothelial growth factor and placental growth factor were measured by enzyme-linked immunosorbent assay in cross-sectional and longitudinal cohorts of pregnant nulliparous women.
