Professor Henry Kitchener:

My initial comment was that there is no reason to believe that the missing slides would be materially different in nature to the large number of slides that were found. I would expect to see similar proportions with discordant results and similar proportions with concordant results. I do not think it would have affected the result. We would have liked every single slide to have been available for review but the fact that some were not would not, I think, have altered our conclusions.
