Abstract:
|
Life table analysis is an essential tool of occupational epidemiology. Most life table analysis systems (LTAS) are limited by platform or analysis options. A new LTAS was created for Windows (LTAS.NET) to permit the analysis of more than one exposure variable, and to allow stratification by fixed and time-dependent covariates. LTAS.NET is written in Microsoft Visual Studio.NET using SQL Server. Options for statistical analyses include indirectly and directly standardized rate ratios, confidence intervals based on Poisson and exact methods, and trend tests for linear associations. LTAS.NET allows simultaneous stratification and analysis of multiple exposure variables. Time-dependent and fixed user-defined variables can be incorporated. The import, stratification and reporting options are highly flexible. Stratified event and person-time data are exportable for use in Poisson regression.
