Analysis of covariance results for comparison of juvenile and zebrafish embryo toxicity pesticide datasets based on chemical mode of action

Mode of action	y intercept	r²	Slope
AChE neurotoxicity	−1.1^*	0.64	0.63^a
Electron transport inhibition	−0.85
Narcosis	0.26^*
Non-AChE neurotoxicity	−0.30^*
Reactivity	0.46^*

Significant difference in y-intercept among mode of action groups: p < 0.05.

^a.

There is a single slope for the entire dataset because the model with 1 slope was not significantly different (i.e., showed lower explanatory power) than the model with multiple slopes for different mode of action categories.

AChE = acetylcholinesterase.
