Abstract
Aim: Software for biostatistics: STATA is introduced. In addition, as an example, multiple imputations were also introduced.
Methods: A total 1,271 pregnant women were enrolled in this prospective cohort study. Outcome was set for Child behavior check list (CBCL) at 3 years of age. Multiple imputations were used to adjust for missing data.
Results: Longer maternal education years were associated with better CBCL. On the other hand, smoking during pregnancy was associated with worse CBCL even after multi-variate adjustment.
New evidence: STATA is useful in analyses of clinical studies.
The textbook titled [Introduction of clinical data analysis using STATA] will be published in June 2014.
