Plot of measured log2 ratios compared to theoretical values for specific chromosomes or chromosomal regions. Plot of average measured log2 ratios compared to theoretical values for six specific chromosomes or chromosomal regions; the CDKN2A locus in 9p21.3, 9p21.3-p21.2, chromosome 2, chromosome 8, 1q (all in TC-32) and the MDM2 locus in 12q15 (in OSA) (representing 0, 1, 2, 3, 4 and >10 copies, respectively) for all microarray platforms and replicates. The slope and regression coefficient (R2) for the regression line based on four of the regions, representing 1, 2, 3 and 4 copies, are given.
