1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Dietary protein restriction during gestation has been shown to produce vascular dysfunction in pregnant rats and hypertension in their offspring. However, no studies have to date examined the effects of such 'programming' on the vascular function of female offspring when they in turn become pregnant. We have therefore studied isolated conduit and resistance artery function from pregnant female offspring of control (C, 18 % casein) and protein-restricted (PR, 9 % casein) pregnant dams. There were no differences in birth weight, weight gain during pregnancy, litter size, fetal weight, placental weight, fetal : placental weight ratio or organ weights between the C and PR groups. In isolated mesenteric arteries, the vasodilatation in response to the endothelial-dependent vasodilator acetylcholine (ACh) and the beta-adrenoceptor agonist isoprenaline was decreased in the PR group, while there were no differences in the constriction in response to potassium (125 mM) or the alpha1-adrenoceptor agonist phenylephrine (PE). No differences in any responses were seen in the isolated thoracic aorta. We conclude that dietary protein restriction in pregnancy programmes vasodilator dysfunction in isolated resistance arteries of female offspring when they become pregnant, but does not affect conduit arteries.
