Table 3 Nine factors for linear regression

ln3

Target's 3' UTR length

0~1

cs3

Target's overall 3' UTR conservation

0~1

exp

Target's mRNA expression level as measured by RNA-Seq.

0~1

#site_m

The number of miRNA or siRNA target sites in the target's 3' UTR

0~1

#endo_m

The number of target sites for endogenous miRNAs in the target's 3' UTR

0~1

#site_s

0~1

p_ma

Binary variable stating whether the target's fold change was measured by microarray or proteomics

1: Microarray

0: Proteomics

e_oe

Binary variable stating whether the target's fold change was measured after miRNA transfection or inhibition

1: Transfection

0: Inhibition

ts_score

mRNA level TargetScan scores. Only used in the last regression model.
