Through correspondence with the authors (Ojaj rvi et al.), I learned that their analysis excluded the many epidemiological studies that had been conducted on workers in the...

There is, however, one rapidly expanding area of research that...

Without expressly intending to do so, however, the article also emphasizes the hazards of establishing formal criteria or checklists for the evaluation of scientific work. Good epi...
