Application of methods used in survival analysis to growth and nutritional studies.
Three statistical methods are described and illustrated with working examples. Using these methods it is possible to include all subjects involved in cross-sectional studies in calculations of results, even if the data are incomplete at the end of the investigation. The use of censored data is taken from survival analysis. It is shown that combination of the Kaplan-Meier estimate, the log-rank test and the proportional hazards model gives more satisfactory results in nutritional and growth studies.
