Plot of measured log 2 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.
