a significant trendP = 0.012
For male rat blood leukocytes (both modulations), results from scoring 100 cells were negative; however, equivocal responses were seen with the 150‐cell method based on a significant trend test ( P = 0.012) or pairwise test ( P = 0.021) for CDMA‐ and GSM‐exposed rats, respectively (Tables 1 and 2 ).
