Effects of vitamin E deficiency on vasomotor activity and ultrastructural organisation of rat thoracic aorta.
Article in British journal of pharmacology, 1995. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
1. The effects of vitamin E deficiency were evaluated in aortic rings isolated from rats maintained on a diet deficient in vitamin E. 2. Endothelium-dependent vasodilator responses to acetylcholine (ACh) and calcium ionophore, A23187, were reduced in preparations from treated animals, compared to the age-matched controls. The maximal vasodilation to ACh was 66.4 +/- 9 (n = 4) and 38.8 +/- 7 (n = 4) % in control and 10 month-treated preparations, respectively. 3. The endothelium-independent vasodilator responses to sodium nitroprusside as well as the concentration-dependent contractile responses to noradrenaline, did not differ between treated and control preparations. 4. Electron microscopic examination of vascular segments and revealed that, following vitamin E deficiency, normal tissue organisation was disrupted, the endothelial monolayer either not being in contact with the underlying tissue or being absent in most of the areas analysed. 5. It is concluded that during vitamin E deficiency both morphological disruption and functional impairment of endothelium occur without observable modification of muscle cell function and morphology.
