We tested 129 metabolites against clinical complications by logistic regression (linear regression for quantitative eGFR). On the x-axis, we report odd ratios (effect sizes for eGFR) in metabolite standard deviation units, whereas the y-axis presents the observed analytical P-values. Red circles highlight metabolites with Pperm <0.05 calculated using 100,000 permutations. In total, we found 2 metabolites for painful crises, 2 metabolites with cholecystectomy, and 62 metabolites for eGFR.
