Trends in antidote use in France from 2015 to 2021: a nationwide poison centers study.
Article in Scientific reports, 2025. 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
The French Poison Centers database is a tool of choice for the analysis of poisoning cases requiring the administration of an antidote although not all uses are systematically reported. This national retrospective study aims to report trends of use of antidotes in France over a 7-year period from 2015 to 2021. A total of 25,289 cases of poisoning required the administration of an antidote, among which 46.7% were moderate to severe. While 77.1% of poisonings progressed toward recovery, the observed mortality rate was 1.7%. The 3 most frequently used antidotes according to data from Poison Centers were N-acetylcysteine (n = 13,555 [53.6%]), flumazenil (n = 3102 [12.3%]) and naloxone (n = 1740 [6.9%]) reflecting the most common types of poisoning involving acetaminophen, benzodiazepines, and opioids. The observed use of methylthioninium chloride, hydroxocobalamin, cyanocobalamin and DOAC reversal agents increased, both in terms of absolute numbers and proportions, revealing new behaviors leading to poisoning, such as nitrous oxide consumption. Conversely, the observed use of ethanol-based therapy, L-carnitine, and dantrolene decreased over time, reflecting both current medical practices and shifts in guidelines. This study provides a novel insight into the typology (circumstances, severity, development) of poisonings requiring an antidote, as well as the description of the causative agents.
