查询词典 variance analysis

Methods RPE cells were exposed to shear stress of 2 dyne/cm2 for 0, 0.25, 0.5, 0.75, 1, 1.5, and 3 h. Reverse transcription polymerase chain reaction was used to detect the levels of c-fos and c-myc mRNA in RPE cells. One-way analysis of variance was used to compare the differences.
