Study Groups

Vitamin D and calcium supplement

Group Type ACTIVE_COMPARATOR

400IU cholecalciferol and 500mg of elemental calcium as calcium carbonate

Intervention Type DRUG

The patients allocated to the intervention group will have a test for serum vitamin D, and receive 800 IU of vitamin D and 1000 mg of calcium as calcium carbonate when the serum vitamin D is decreased. The patients in the control group will be followed up without intervention for one year.

Control

Group Type NO_INTERVENTION

No interventions assigned to this group
