Estimate of potency versus the maxmMd. An estimate of potency, or benchmark dose ($\text{BMD}$) is compared to the maxmMd value. The $\text{BMD}$ (μM) is the concentration at which the Hill fit of the $\text{mMd}$ data intersects with the critical value for a given chemical. A loess smooth regression line demonstrates a general relationship between $\text{BMD}$ and maxmMd. A table summarizing the effects of a Spearman-based trend analysis versus negative and positive maxmMd values is provided in the upper right. Light blue squares = negative maxmMd response and no trend (48 chemical samples); dark blue diamonds = negative maxmMd response and trend (3 chemical samples); orange triangles = positive maxmMd value and no trend (308 chemical samples); red circles = positive maxmMd value and trend (407 chemical samples).
