Example regression profiles. Example regression profiles based on microarray data from a gene that does not appreciably deviate from baseline until Day 28 in 50 nM T₄ (A; collagen, type VI, alpha 3; probe-set ID: SRV_05103_a_at) and a gene that is initially up regulated in 50 nM T₄ before being down regulated (B; N-Myc downstream regulated gene 1; probe-set ID: SRV_12417_at). Trend lines for the 5 nM regression analyses are gray and trend lines for the 50 nM regression analyses are black. LU = linear up and QLCD = quadratic linear concave down.
