Table 2. Average inflammation observed in the H&E slides separated into regions expressed as a percentage of the total area.

Values are the mean and standard deviations, and the p-values are from unpaired t-tests with Welch’s correction for uneven variances. All comparisons were significantly different between the LPS and control groups (p<0.05).

	LPS group (n = 7)	Control group (n = 4)	p-value
Whole lung (six slides per rat)	4.6 ± 1.6	0.4 ± 0.7	0.0003
Left lung (three slides per rat)	5.3 ± 2.7	0.5 ± 0.7	0.0026
Right lung (three slides per rat)	3.8 ± 1.3	0.4 ± 0.7	0.0003
Upper region (two slides per rat)	4.4 ± 1.9	0.4 ± 0.7	0.0009
Middle region (two slides per rat)	5.9 ± 5.5	0.6 ± 0.9	0.0440
Lower region (two slides per rat)	3.5 ± 1.7	0.4 ± 0.5	0.0018
