I read with interest and confusion the article by Schrader et al. 2008 reporting spindle disturbances following RF exposure. On page 631, the article states that "...cells were analyzed for controls which were kept unexposed either at 37 癈 or parallel with the RF radiation exposures at room temperature of 20-22 癈." On page 632, the authors refer to the comparison of exposed to "co-incident negative control data" particularly in reference to Table 1. Table 1 presents data as a function of time of exposure for two experiments. The variation with time for the two experiments is similar. If the authors are referring to zero time as the control in Table 1, then there is no control at all. I find no true sham-exposed control data, that is, no data from
