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

backgroundMany case reports of acute caffeine intoxication have been published, but there have been hardly any systematic data analyses, nor have there been any prospective studies, representative epidemiologic studies, or guideline recommendations. In this review, we aim to describe the clinical entity of acute caffeine intoxication and its treatments to date on the basis of published case reports.

methodsThis review is based on pertinent case reports retrieved by a search in the PubMed, Google Scholar, and Semantic Scholar databases covering the period 1851-2023 and employing the keywords "caffeine intoxication," "caffeine poisoning," and "caffeine overdose."

results216 published individual cases were analyzed. The median caffeine intoxication dose was 12 g (0.05-106 g), and the median serum caffeine concentration was 160 mg/L (15.6-1560 mg/L). The intoxication was deliberate with suicidal intent in 40% of cases, accidental in 22%, and a treatment error in 6%. 21% of the accidental intoxications were in minors. Convulsions and wide-complex tachycardias due to intoxication were associated with a worse outcome, and extracorporeal hemodialysis appears to be a safe and effective way to eliminate caffeine, with a better survival rate even after severe intoxication. Doses of 5-10 g of caffeine can be lethal.

conclusionThis is the largest analysis of caffeine intoxications ever carried out to date, yet no defin - itive treatment recommendations can be derived from it. Caffeine elimination by hemodialysis can be considered if the quantity ingested is potentially lethal, or in cases with a severe clinical course.
