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

purpose of reviewThis review examines the perioperative implications of selected substances in the contemporary unregulated drug supply and outlines a physiology-based approach to preoperative assessment, risk recognition, and postoperative pain management. RECENT

findingsPatients may be exposed intentionally or unknowingly to fentanyl and nitazenes, xylazine and medetomidine, kratom and concentrated 7-hydroxymitragynine products, tianeptine, phenibut, and other psychoactive substances. Clinically important patterns include respiratory depression, prolonged sedation, bradycardia, hypotension, opioid tolerance, withdrawal, and difficult postoperative pain. Polysubstance exposure, uncertain product composition, and limitations of routine toxicology screening may complicate identification of the responsible substance. Perioperative assessment should emphasize specific, nonjudgmental history taking, recognition of physiologic patterns, and individualized risk stratification rather than reliance on identification of a specific substance. Perioperative planning should integrate physiologic findings with the limitations of toxicology testing and distinguish surgical pain from tolerance, withdrawal, opioid-induced hyperalgesia, and delirium. Awareness of a geographically variable and rapidly evolving drug supply is increasingly important for safe perioperative care.
