The delimiters for fold change variability. We estimate the borders of the left part of the rhomboid by fitting on the data two hyperbolas. In the comparison between two technical replicates, the curves enclose almost all the points (a), while between two samples in a case-control study, the differentially expressed genes fall outside the boundaries. These curves act as a fuzzy threshold for the significance DE events
