Pre-analytical factor effects on the children’s metabolome. a Postprandial effects on serum metabolites (adjusted for age, sex, zBMI)—meta-analysis after stratifying by cohorts with estimates representing the change in metabolite SD per hour postprandial and error bar indicating 95% confidence interval. b Diurnal effects on urine metabolites. Only t test adjusted p < 0.05 are shown (n = 48 for morning and n = 37 for night samples). The estimates indicate the standardised mean differences between the morning and night samples, with the error bars indicating the 95% confidence intervals. Metabolites found higher in the morning void samples are shown as positive and metabolites found higher in night-time void samples are shown as negative
