The National Acadamy of the Sciences is not just some random "independent" group. Of course, the article states that it's still unclear as to whether they will take more data, or simply review existing studies. Likely, they will do a review first to decide if further study is necessary (e.g., if the methodology used in prior studies was, in fact, unsound). In any case, having unaffiliated scientists consider the issue is a step in the right direction.
