Daytime and night-time urine in the SKIPOGH population (n= 925). A. Distribution of mUosm among SKIPOGH subjects. Thin curves represent the normal distribution model. B. Linear correlation between measured and estimated Uosm in daytime and night-time urine. C. Quadratic correlation between UCI and mUosm in daytime versus night-time urine. In B and C, black lines represent the best-fit curves and red thin lines 95% confidence intervals. Dotted lines in B represent the medians.
