Table 4.

Coefficients of ANOVA analysis for relative tissue weights (tissue/body weight) in different groups taken on day 14 post exposure [(values are modified based on pre-exposure and control values to remove the effects of confounding variables. Combined effects (synergism, antagonism) were calculated as described in a study by Piggott et al. (30).]

Tissue	Noise group	Toluene group	Combined group	Interaction type
Heart	0.075±0.279	-0.146±0.279	0.222±0.279	+Synergism
Lung	-0.416±0.506	0.488±0.506	0.120±0.506	-Antagonism
Spleen	-0.264±0.116	0.121±0.116	0.203±0.116	+Synergism
Stomach	-1.611±0.891	0.056±0.891	0.850±0.891	+Synergism

All values are the coefficient value ± SE (standard error of coefficient)
