1 Quality control samples (QCs)

1.1 Data

This table does not contain ratios/indexes calculated from the measured metabolites.

1.2 Descriptive statistics

This table does not contain ratios/indexes calculated from the measured metabolites.

Abbreviations:

  • n: number of measurements
  • IQR: interquartile range; measures the spread of the middle half of the data when values are ordered from lowest to highest
  • gMean: geometric mean
  • gSD: geometric SD
  • gSDrange: geometric SD range (1 SD range); calculated by dividing and multiplying the geometric mean (gMean) with the geometric SD factor (gSD) to obtain the lower (gSDlower) and upper (gSDupper) limits, respectively
  • CV, %: study-specific coefficient of variation in percentage from untransformed values
  • gCV, %: study-specific coefficient of variation in percentage from log-transformed values
  • gCV, s%: study-specific coefficient of variation in sympercent (symmetric and additive percentage) calculated from the natural logarithm of SD multiplied with 100 (logSD x 100)

1.3 Coefficients of variation (CVs)

The table shows CVs specific to your study, which have been calculated using repeated QC samples.
Study-specific CVs may not be calculated for all the measured metabolites.
This table does not contain ratios/indexes calculated from the measured metabolites.

Abbreviations:

  • n: number of measurements
  • gCV, s%: coefficient of variation in sympercent (symmetric and additive percentage) calculated from the natural logarithm of SD multiplied with 100 (logSD x 100)

1.4 CV limits

1.4.1 All measured platforms

This plot shows the proportions of metabolites below/above certain limits of CVs.


The plot is based on your study-specific CVs from section 1.3.
Study-specific CVs may not be calculated for all the measured metabolites.
This plot does not include ratios/indexes calculated from the measured metabolites.

1.4.2 Separate platforms

These plots show the proportions of metabolites below/above certain limits of CVs within platforms.





These plots are based on your study-specific CVs from section 1.3.
Study-specific CVs may not be calculated for all the measured metabolites.
These plots do not include ratios/indexes calculated from the measured metabolites.
