Reply: Vertical segmental tetrapolar bioimpedance for excess body fat assessment in adolescents.

The questions presented by Professor Dr. Roberto Fernandes da Costa and Dr. Edilson Serpeloni Cyrino are relevant and, Regarding the statistical analysis, we used a stringent sampling procedure and data that met specific requirements, namely: (a) the dependent variables were quantitative and continuous, and were measured in at least one interval scale; (b) there was homoscedasticity based on Levene’s test (homogeneity of variance); (c) the sample size was large and came from a population with normal distribution. We believe, therefore, that there was agreement with the central limit theorem. It is noteworthy that especially for large samples, the parametric tests (Student’s t-test and ANOVA) are more sensitive and have a more robust behavior even when the distribution of the study variable shows heteroscedasticity and is demonstrably not the normal type.5
