Fig 1. Effect of PM 2.5 exposure on body weights in BN and JCR/LA rats.
A. Body weights in BN rats compared to JCR/LA rats. There were no treatment differences, but only strain differences. B. Body weight differences between the 2 age groups of JCR/LA rats. Older rats were heavier than the younger rats. There were no treatment differences. ‘a’ indicates p<0.05 compared to BN rats or younger JCR/LA rats.
