Norman Yarvin 15 Apr 2010 11:27 am The only problem is, when The only problem is, when you look up the study he references, you find that: The proper citation is "Acta Med Indones. 2006 Jan-Mar;38(1):3-5", not "Acta Med Indos. Jan-Mar 2006;36(1):3-5". It was 67 patients, not 70. Half of them were in the placebo group, so only 34 were on vitamin D. They were all receiving conventional anti-TB therapy at the same time. The criterion for success was "sputum conversion" (which I think means no longer coughing up TB germs), not "complete recovery". Even the people who achieved "sputum conversion" still had some nasty-looking lung X-rays. The placebo group mostly succeeded too: at six weeks, where the vitamin D group had 100% sputum conversion, the placebo group had 76.7% sputum conversion (due, of course, to the conventional therapy that both they and the vitamin D group were on). Of the eight remaining patients, seven succeeded by the eighth week of therapy, and the remaining one succeeded at 12 weeks. In sum, the result of the study is best described as "Vitamin D helps a bit", not as "Oh my god, it's a miracle cure". Oh, and that "Dr. Howenstine" website should never be trusted on anything ever again.
