Table 2 Comparison of miRNA expression between microarray and qPCR-array basedon GC content and Ct value

From: Reproducibility of quantitative RT-PCR array in miRNA expression profiling and comparison with microarray analysis

   Number of miRNA Correlation coefficient p value*
GC contents (%) >30 to 45 25 -0.413  
  >45 to 55 41 -0.403  
  >55 18 -0.490 0.8988
Ct value >20 to 25 9 -0.709  
  >25 to 30 55 -0.428  
  >30 to 35 20 -0.108 0.0428
  1. *Test of equivalence of correlations.
  2. p value for >25 to 30 compared to >30 to 35, >20 to 25 excluded from test due to small sample size in group.
