* 66 metabolites ** 61 metabolites Mean ± SD: Each metabolite is scored relative to the standard pool, then each individual sample is assigned one value (the mean of its metabolites averaged across the duplicates and triplicates) and these means are then expressed as mean ± SD Mean Median: Average of the medians of the 66/61 variables across the population Mean CV: Average of the CVs of the 66/61 variables across the population Median CV: Median of the CVs of the 66/61 variables across the population
