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

Alzheimer's disease is the most frequent type of dementia and diagnosed late in the progression of the illness when irreversible brain tissue loss has already occurred. For this reason, treatments have been ineffective. It is imperative to find novel therapies ameliorating modifiable risk factors (hypertension, stroke, diabetes, chronic kidney disease, and traumatic brain injury) and effective against early pathogenic mechanisms including alterations in cerebral blood flow leading to poor oxygenation and decreased access to nutrients, impaired glucose metabolism, chronic inflammation, and glutamate excitotoxicity. Angiotensin II receptor blockers (ARBs) fulfill these requirements. ARBs are directly neuroprotective against early injury factors in neuronal, astrocyte, microglia, and cerebrovascular endothelial cell cultures. ARBs protect cerebral blood flow and reduce injury to the blood brain barrier and neurological and cognitive loss in animal models of brain ischemia, traumatic brain injury, and Alzheimer's disease. These compounds are clinically effective against major risk factors for Alzheimer's disease: hypertension, stroke, chronic kidney disease, diabetes and metabolic syndrome, and ameliorate age-dependent cognitive loss. Controlled studies on hypertensive patients, open trials, case reports, and database meta-analysis indicate significant therapeutic effects of ARBs in Alzheimer's disease. ARBs are safe compounds, widely used to treat cardiovascular and metabolic disorders in humans, and although they reduce hypertension, they do not affect blood pressure in normotensive individuals. Overall, there is sufficient evidence to consider long-term controlled clinical studies with ARBs in patients suffering from established risk factors, in patients with early cognitive loss, or in normal individuals when reliable biomarkers of Alzheimer's disease risk are identified.
