Comparison of small center distance fraction measures by (a) genotype, (b) sex and (C) by both genotype and sex for wild-type WT and HIV-1 transgenic (Tg) rats in the four exposure groups. There were no overall differences in the measures by genotype (a). For females in the CON and NIC groups, the measures were higher for females than for males. Comparison of the measures by both genotype and sex showed higher measures for WT females than for Tg males in the CON group and higher measures for WT females than for WT and Tg males in the NF group. Borderline statistically significant higher levels were found for WT females as compared to WT males in the CON group and for WT females as compared to Tg females in the NF group. CON = control; NIC = subcutaneous nicotine; NF = nicotine-free cigarette smoke; CIG = regular cigarette smoke.
