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

Caffeinated drinks are the most widely consumed beverages globally and their intake has increased in the elderly. Caffeine exhibits dose-dependent adverse effects. Low to moderate doses cause anxiety, restlessness, irritability, and nausea. High doses of 3-5g can affect different physiological systems and lead to detrimental effects like palpitations, hypertension, agitation, seizures, and coma. Low-dose aspirin is the most used anticoagulant in preventing ischemic vascular events. An increased risk of intracranial hemorrhage is associated with low-dose aspirin with an intensified intracerebral hemorrhage risk. The aim of this research is to explore the association between caffeine and aspirin in causing lethal intracranial hemorrhage in the older population. Because of the devastating nature of intracranial hemorrhages and the inconsistent published data on the risk of intracranial hemorrhage in individuals taking both aspirin and caffeine, we conducted a systematic review considering the elderly population. We conducted the study following the reporting guidelines for systematic review and the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) checklist. Inclusion and exclusion criteria were determined. Data was collected from PubMed, PubMed Central® (PMC), National Library of Medicine (MEDLINE), Google Scholar, Multidisciplinary Digital Publishing Institute (MDPI), and Web of Science by applying keywords and Medical Subject Headings (MeSH) terms individually. Our initial search yielded 155,270 articles, which were scrutinized, and duplicates were removed for accuracy. Of these, a total of 13 research papers were finally extracted using the PRISMA recommendations and applying other inclusion and exclusion criteria. With the help of our systematic review, we could determine that both aspirin and caffeine portrayed a role in causing intracranial hemorrhage independently, but further studies are recommended to evaluate if both could lead to similar adverse effects when taken collectively.
