Control and Restricted rats were randomized to normal salt or high salt diet for 6 weeks at 20–26 weeks of age. No significant interactions between diet and uteroplacental insufficiency surgery by two‐way ANOVA; n = 10–11 per group. NS, not significant; OD, outside diameter; ID, internal diameter; WT, wall thickness; M:L, media‐to‐lumen.
