Comparison of ranks of targeted and non-targeted mass spectrometric measurements of pseudouridine and creatinine as well as respective composite measures of pseudouridine in individuals without CKD. (A) Pseudouridine, (B) Creatinine, (C) Urinary pseudouridine-to-creatinine ratio, (D) Fractional excretion – original version: using creatinine measurements from respective platform, i.e. targeted or non-targeted, (E) Fractional excretion – adapted version: using standard clinical laboratory measurement of creatinine. SCC: Spearman correlation coefficient corresponding to slope of displayed regression line of rank-transformed measurements.
