Centile Calc Indiv UK 5.1

For each of the datasets, coefficients affecting birthweight were obtained using a backwards conditional multiple regression technique. This software calculates customised birthweight (per)centiles using the principles of the Gestation Related Optimal Weight (GROW) program. The latest versions give the option of customisation based on datasets from UK (N=40,000), Sweden (N=400,000), New Zealand (N=5,000), Australia (N=12,500) and United States (N=35,000).
