Comment by VitaminDWiki

Suspect that this RCT will fail to get enough people willing to limit their levels of vitamin D.
Patients have not wanted to limit their vitamin D in several RCT in 2012 and 2013, so they were cancelled
4,000 IU may be enough Vitamin D for those who are not at high risk of being vitamin D deficient – such as elderly, darker skinned, obese, or shut-ins

They are advertising in Craigs list (Jan 2014) - trying to get participants

One of the reasons is that this RCT is being widely announced - so lots of people are strongly suspecting the vitamin D will help
