Maternal salt diet has little effect on feto-placental tissues in late gestation.

Data are estimated marginal means plus the standard error of the differences between means (s.e.d.). At day 20, data are n = 10 dams per dietary group (Control, n = 4 male/female pups; 4% salt diet n = 7 male and n = 4 female pups). At term, data are n = 8 control and n = 5 SD dams (Control, n = 8/8 male/female pups; SD diet, n = 7/5 male/female pups). Data were analysed by mixed effects models with treatment (control vs. 4% salt), sex (male vs. female) and age (day 20 vs. term) or their interaction as fixed effects and dam as a random effect (Genstat v14). Log10 transformation was used before analysis, as required, to achieve normality in error distribution. NS, not significant. −ve, is control diet (CD). +ve, is 4% salt diet (SD).
