Careful, you’re misinterpreting the document. The two studies you’ve picked are listed as “neither evidence of an effect or a null finding”, they are not included in the “more than 500 studies” finding harmful effects. Those studies are prefixed by “P” in the document and, although I haven’t counted, a rough estimate based on the number of pages makes it plausible that there are > 500.

That said, given the scientific consensus from rigorous meta-analyses, I expect that these “positive” studies are mostly of low quality and/or limited sample size. And scepticism is generally warranted when advocates start listing large numbers of studies instead of referring to a few meta-studies. As it happens, the best available meta-studies come to the opposite conclusion (namely, that there’s probably no harm from mobile EMF), so this long list is essentially bogus.
