I disagree with your interpretation of the statistics. There are going to be inter-group differences with any controlled study. This is sampling error and it's exactly what the p-value and confidence intervals are meant to account for.

It's unlikely that the strongly significant result we're seeing in the study is due to sampling error.

I don't think it is all due to sampling error. In my article I mention that one of the areas in which Vitamin D shows promise is with respiratory illness. I think there likely is an effect, just not as dramatic as the headlines are making it.
