Urine metabolites reflect patterns of health and lifestyle. a Heatmap whereby each cell represents the strength of correlation between daily average metabolite intensity and each biometric data collected from smartphone apps. Repeated measures correlation³³ was used where data was available for both subjects whereas Robust Spearman’s Correlation³⁴ was used for data only available for Subject 1 (i.e., exercise and sleep). b An example correlation (r = 0.812, p = 1.32e−4, q = 0.0120, dof = 14) between alcohol consumption (in kcals) and a carbohydrate compound (“carbohydrate 6”), most likely representing xylitol. An interactive version of b is provided in the companion webtool
