". . . they have mixed apples and oranges—and sometimes “apples, lice, and killer whales”—yielding meaningless conclusions"

It does not mention the major problems of Vitamin D Meta-analyses. 1) Dose sizes are ignored: Studies assume benefit from 400 IU is the same as for 4,000 IU2) Durations are ignored: Studies assume benefit of 1 month dosing is the same as 1 year dosing3) Existing Vitamin D levels are often ignored.   Studies ignore that a 20 ng addition to a 10 ng person has vastly more benefit than a 20 ng addition to a 40 ng personA rare example of a good meta-analysis is: one on depression - April 2014Really great medical studies do not blindly give a single supplement/drug to a group, but rather treat the patients as individuals and provide extra Magnesium, Vitamin K2, Omega-3, Vitamin C, etc as needed. These studies, which have the best results, are not Random Controlled Trials and are virtually never included in a meta-analysis.Likewise, the trials which give vitamin D to an entire country, or to all of the patients (immoral not to do so) are never considered by any meta-analysis
