Brief summary

Retrospective database analysis. The target values are the serum values of 25(OH)D, of 1,25(OH)2D, of magnesium and creatinine as well as age and sex of the patients. The laboratory values of the years 2017 and 2018 are included. There are no additional measurements on patients.

Detailed description

The laboratory values of the years 2017 and 2018 are included. All laboratory results to be evaluated originate from Medics Labor in Bern. We expect about 50'000 data sets. It is impossible for the study team to draw conclusions about the patients or the senders.
