Table 1. Introns significantly different with regard to intron retention between chd1Δ and WT, when all introns in the yeast genome were considered.

	This study, number of introns	Lee et al., (26) number of introns
OR < 1, lower intron retention in chd1Δ	28	98
OR > 1, higher intron retention in chd1Δ	7	6

OR is the odds ratio (see ‘Materials and Methods’ section).
