Table 3 Regression models for Est[Na/Cr]U24, and Est[K/Cr]U24 in the validation group (n = 34)

From: Estimation of daily sodium and potassium excretion from overnight urine of Japanese children and adolescents

 

Slope (95% confidence limits)

Intercept (95% confidence limits)

ln(Na/Cr +1)

1.0148 (0.5177, 1.9943)

0.2085 (−0.4007, 0.5393)

ln(K/Cr +1)

1.3165 (0.8290, 3.0075)

0.0315 (−0.3682, 0.1501)

  1. Est[Na/Cr]U24 and Est[K/Cr]U24: estimated ratios of sodium to creatinine and potassium to creatinine in 24-h urine
  2. Passing-Bablok regressions were used for natural log-transformed variables. Units for Na (sodium), K (potassium), and Cr (creatinine) were mEq L−1, mEq L−1, mg dL−1, respectively
