Table 5 PC21 Tissue Partitioning and Ordering. Partitioning and ordering of tissues into sets UP ₂₁ (n = 8) and DOWN ₂₁ (n = 20) sets found to have significant expression differences for H ₂₁ and L ₂₁ at test1Thresh = 0.05. Tissues within groups are ordered by decreasing abs(mean (H ₂₁ )–mean(L ₂₁ )), which has the effect of placing the most significantly affected tissues at the top of each list. The most significant tissues in UP ₂₁ are at the left of Figure 4, and the most significant conditions in DOWN ₂₁ are at the right of Figure 4.
