Effects of chronic 50 ppm eugenol treatment and time (cumulative duration of chronic exposure) on C. bombi cell morphology in vitro.

A. Area	χ2	df	P
Eugenol	52.801	1	<0.001
Eugenol × Time	48.422	2	<0.001
B. Length	χ2	df	P
Eugenol	38.136	1	<0.001
Eugenol × Time	32.203	2	<0.001
C. Width	χ2	df	P
Eugenol	31.829	1	<0.001
Eugenol × Time	47.327	2	<0.001

At each time point, we measured (A) area, (B) length, and (C) width of 20 cells for each of 5 cell lines per treatment.
