Brief summary
There is no validated self-questionnaire to assess salt and potassium intake in nephrology patients. Using Bayesian models, researchers developed clinical prediction tools to estimate salt and potassium intake in nephrology patients. These prediction tools performed well, with an accuracy of 89% for salt and 74% for potassium, and have undergone internal validation. Currently, the investigators wish to conduct an external validation study of these clinical prediction tools using data from patients followed at 3 nephrologic centers to generalize the performance results of the tools.
Interventions
Questionnaire will be compared to 24h sodium and potassium urinary excretion (reference). A Bayesian network and a multiple regression will be used to validate the questionary
