Descriptive statistics for the human IGF-1 splice variants mRNA compositional ratios

	Min.	1st quartile	Median	Mean	3rd quartile	Max.
Ratio 1 (IGF-1 Ea)	0.6560	0.8000	0.8335	0.8276	0.8733	0.9293
Ratio 2 (IGF-1 Eb)	0.06916	0.10820	0.13910	0.15380	0.17750	0.32690
Ratio 3 (IGF-1 Ec)	0.000721	0.007274	0.014130	0.018560	0.023310	0.063630

Ratio 1 $=\frac{\left[Ea\right]}{\left[Ea\right]+\left[Eb\right]+\left[Ec\right]}$; Ratio 2 $=\frac{\left[Eb\right]}{\left[Ea\right]+\left[Eb\right]+\left[Ec\right]}$; Ratio 3 $=\frac{\left[Ec\right]}{\left[Ea\right]+\left[Eb\right]+\left[Ec\right]}$

Descriptive statistics for the observed human IGF-1 splice variants mRNA compositional ratios in the cohort of 20 different human tissues. Minimum, maximum, 1st quartile, median, 3rd quartile and mean are shown for each compositional ratio. Compositional ratios are defined in the lowest part of the table
