Variables that were skewed were logarithmically transformed before entering the regression analysis.
Variables with normal distribution are expressed as mean ± standard deviation while variables with a not normal distribution are expressed as median and interquartile range and were log transformed before entering the statistical analysis.
This transient is subtracted from the input signal in order to ensure that this intra-frame transient is removed as much as possible before entering the sinusoidal and noise analysis, since these stages operate under the assumption that the input signal is quasistationary.
Before entering the data into cluster analysis, we linearly transformed the scores on the three scales into standardised z scores, to enable their direct comparison.
Before entering the hemodynamic variables into the statistical analysis, the variable time integral during the first 24 hours was calculated for all parameters.
On the one hand, all the cases exposed before 1940 entered the analysis with a latency of at least 38 years, as all deaths that occurred before 1978 were left censored.
Women diagnosed with ovarian cancer before entering the cohort (n = 14) or before 1989 (n = 13), were excluded from the analysis.
For gas chromatography mass spectrometry (GC MS) analysis, the products pass directly through the GC column before entering the MS source.
