Henry, I think the translation was fine. Since they were woinrkg in medians and not means, really have to dig into the results. In the vitamin D group, the median size of ulcer started at 25cm2, then reduced to a median 18cm2. For placebo group, the numbers were 27cm2 to 24.5cm2, respectively. I think this is where you"re getting your 38% and 9%. However, these findings were not statistically significant (p=.71, .79), so I think it"s unfair to make too much of total reduction in ulcer size.When the researchers analyzed patients on a case-by-case basis, measuring ulcer size pre-treatment and post-treatment, the median patient"s ulcer size decreased by 4cm2 in the vitamin D group, the median patient"s ulcer size increased by .75cm2 in the placebo group. The statistical significance was much better here (p=.06, considered trending ).Also, not sure where you"re pulling the 4x faster number from? Since we do not know if either groups" ulcers fully healed (in a condition that may ta
