Reversal of left ventricular hypertrophy by propranolol in hypertensive rats.
Article in African health sciences, 2005. 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
backgroundHypertension contributes significantly to the development of left ventricular hypertrophy. Left ventricular hypertrophy is associated with increased incidence of sudden cardiac death. Recognition and management of hypertension is, therefore, imperative.
objectiveTo establish whether propranolol can reverse left ventricular hypertrophy in hypertensive rats.
methodsHypertension was induced in male albino rats by giving them 1% NaCl solution as their only drink for four weeks. Propranolol was then administered orally to one of the four groups of rats used in this study. Systolic blood pressure of each rat was measured twice a week using a modified tail-cuff method. Each rat was then sacrificed, its heart excised from the chest cavity and geometric studies carried on the left ventricle.
resultsExcessive intake of sodium salt by the rats caused an increase in their systolic blood pressure which was accompanied by left ventricular hypertrophy. The elevated blood pressure (139.4 +/- 0.5 mm Hg) was, however, brought back to normal (108.4 +/- 0.2 mm Hg) by propranolol. Data on weight, thickness, and volume of the left ventricle strongly indicated that propranolol can reverse ventricular hypertrophy.
conclusionPropranolol reverses left ventricular hypertrophy besides lowering elevated systolic blood pressure in rats.
