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

Liraglutide (LIRA) is an agonist of the GLP-1 receptor used in the treatment of type 2 diabetes with a cardioprotective effect, although little is known about the effects of LIRA in post-menopause. We aimed to evaluate the effects of LIRA in the cardiovascular system of ovariectomized spontaneously hypertensive rats (SHR). SHR rats were separated into two groups: ovariectomized (saline) and ovariectomized + liraglutide (0.6 and 1.2 mg/kg for 4+4 weeks, respectively). Systolic blood pressure (SBP) was indirectly evaluated at the beginning and end of treatment. Diastolic, systolic, and mean blood pressure were evaluated in the carotid artery of anesthetized animals, while left ventricle systolic blood pressure (LVSBP) and left ventricle derivatives (-dP/dt; +dP/dt) were evaluated in the left ventricle. An oral glucose tolerance test (GTT) was conducted. Antioxidant enzymes and calcium-handling proteins were analyzed in heart tissue by western blot. Treatment with LIRA increased the expression of antioxidant enzymes (superoxide dismutase (SOD2) and catalase). No changes were observed in the GTT, cardiac hemodynamics, blood pressure, and calcium-handling protein expression. A decrease in visceral fat depot was observed without changes in final body weight. LIRA induced an antioxidant subclinical effect in ovariectomized SHR female rats without changing glucose metabolism and cardiac blood pressure.
