简要总结
The aim of the study is to assess the association between the calcium and phosphorus balance and the stage of kidney disease measured by creatinine clearence in patients with chronic kidney disease stage 4 and 5. The balance is measured a measurement between the recorded diatery intake and the urinary excretion. Additionally a comparison between image based diatery accessment and weighted records will be measured
详细描述
All participants will be asked to take photos of all the food and fluids they consume during 24 hours. Additionally participants will be offered to weight their food and fluid for 3 days.
