Identification of tissue-specific and ubiquitous eQTLs. a Fraction of tested eQTLs that load on each factor. b Fraction of eQTLs that load on ubiquitous and tissue-specific factors. c The overlap of tested eQTLs that loaded on the ubiquitous factor (u-eQTLs) and any tissue-specific factor (ts-eQTLs). d Fraction of eQTLs that load on different numbers of tissue-specific factors. eQTLs that load with a specific number of ts-factors can fall into one of two categories: those with the ubiquitous factor and those with only ts-factors. The figure shows the fraction of tested eQTLs that load on each number of ts-factors with colors to show the contribution for each category. e Fraction of eQTLs with activity in different numbers of tissues. The numbers of unique tissues represented in the set of factors for each eQTL are summed
