✦ Synopsis

Classical methods for sampling and analysis of phthalates in air suffer from low sensitivity and high risk of contamination. A new approach based on enrichment on polydimethylsiloxane sorption tubes followed by thermal desorption Ž . and capillary gas chromatography᎐mass spectroscopy GC᎐MS analysis is de-Ž . scribed. The polydimethylsiloxane PDMS support coated traps allow sufficient enrichment while the phthalates can be desorbed quantitatively at moderate temperatures. In combination with capillary GC᎐MS analysis, high sensitivity, accuracy, and repeatability are obtained while the risk of contamination is strongly reduced.

When the role of a new prognostic factor is investigated, careful planning of an appropriate study is required. This includes an assessment of the power of the study in terms of sample sizes. An adequate analysis of the independent prognostic e!ect of a new factor has to be adjusted for the existing
