2.8. Statistics
Results obtained for the test cigarette groups were compared to
the control cigarette group with standard statistical tools. The reference
cigarette 2R4F was only used as an internal reference to
monitor consistency with historical data of the laboratory and
was not included in the statistical evaluation.
3. Results
3.1. Smoke chemistry
The following smoke constituents were below the limit of quantitation
(LOQ) in smoke from control and/or test kretek cigarettes,
and consequently they will not be discussed further: N-nitrosodimethylamine
(NDMA), N-nitrosomethylethylamine (NMEA), Nnitrosodiethylamine
(NDEA), N-nitrosodi-n-propylamine(NPRA),
