Multiple regression analysis of EL, EB and several gene parameters.

Results from multiple-regression analyses of level of gene expression (EL) and breadth (EB) and length (of 5��, CDS, intron, 3�� and primary transcript, PT) when controlling for regional and genic effects. The results for the intron number are also shown. All lengths were log10 transformed.Note. PT = Primary Transcript; n.a. = not applicable; Significance levels: ns = not significant; ��PIn bold: values that are significant after Bonferroni correction for multiple regression. Alpha level was adjusted separately for each type of model: EL,EB: 0.05/2 = 0.025; EL,EB & regional: 0.05/4 = 0.0125; EL,EB, regional+genic = 0.05/9 = 0.0056 (see Mundfrom et al 2006).1regional variables: intergenic spacers length and intergenic spacers GC content. Genes without intergenic spacers were excluded.2genic variables; 5��,CDS,Intron,3��, primary transcript lengths and intron number. Genes without introns were not included in the analyses.3,4genes without introns were excluded from the analyses.
