Figure 2

EA (%RME2) of eleven BPA-replacement resins. Each individual value is the maximum %RME2 that is the mean of 3–4 intra-assay data points for a single assay run on different wells of the same plate (see Methods). The mean (M) and SD (S) values of EA for a given type of assay in a single cell of the table is given when ≥4 independent assays were performed for that given assay condition, i.e., for the cell representing COC D, MCF-7 assay, saline extract, microwave stress. If no assays were run for the conditions associated with a cell in Figure 2, no EA values are given for that cell (i.e., the cell is blank). Many more assays were performed on COP Z resin cpompared to other resins because COP Z resin was used as a negative control in various assays for EA. When four our more individual assays were performed for the variables associated with a given cell, the number of independent assays (n), their mean (M) and their standard deviation (S) are indicated. Yellow highlighted cells, or combination of cells, indicate that at least 3 assays were consistently positive for EA, i.e., exhibited EA significantly greater (p <0.01, Student’s T-test, %RME2 ≥ 15) than VC and SC values (see Methods). A yellow-highlighted resin (e.g., PS) indicates a resin for which at least one cell or combination of cells exhibited EA. Grey-highlighted cells indicate assays using distilled water as an extract solution.
