It seems to consider the benefits of Calcium by itself, and not in combination with vitamin D
'insufficient evidence' seems to indicate insufficient evidence when not combined with vitamin D)
The following is a tiny subset of the information

- Preventing low calcium levels.
- Reversing high potassium levels, when given intravenously (by IV).
- Use as an antacid as calcium carbonate.
- Reducing phosphate levels in people with kidney disease.
Likely effective for...

More evidence is needed to rate the effectiveness of calcium for these uses.
