-Many vitamin D studies suffer from methodological errors including [[home:pathogenesis:vitamind:observational_bias|bias inherent to using self-selected subjects]] and [[home:pathogenesis:vitamind:longterm|insufficient followup]], but perhaps their most egregious liability comes in mistaking correlation for causation. +Many vitamin D studies suffer from methodological errors including [[home:pathogenesis:vitamind:observational_bias|bias inherent to using self-selected subjects]] and [[home:pathogenesis:vitamind:longterm|insufficient followup]], but perhaps their most egregious liability comes in mistaking correlation for causation. (({{pubmed>long:27610068}}))
  
 It's undisputed that a wide array of studies point to the fact that 25-hydroxyvitamin D (25-D) – typically referred to in the media as vitamin D – is low in people with numerous chronic inflammatory diseases. However, these studies fail to prove that low 25-D //causes// disease. Even so, some studies assume that doubling serum levels of 25-D would drastically reduce mortality.(({{pubmed>long:21731036}})) It's undisputed that a wide array of studies point to the fact that 25-hydroxyvitamin D (25-D) – typically referred to in the media as vitamin D – is low in people with numerous chronic inflammatory diseases.
