*β (standardized regression coefficients) and 95% CIs. ATP, adenosine triphosphate; CI, confidence interval; eGFR, estimated glomerular filtration rate; PCr, phosphocreatinine; Pi, inorganic phosphate. Boldface indicates significant values. Statistical significance is indicated by boldface for P < 0.05.
