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

Narcotic scent mimics, which are chemicals that emit a perceivable scent similar to that of the illicit drug but do not possess the health and addiction risks of the drug, have applications ranging from canine training in law enforcement agencies to antinarcotic public education. However, low-cost and easily accessible formulation and delivery systems for narcotic scent mimics have thus far been lacking. In this work, we assess the potential of synthetic (metal-organic framework, MOF) and natural (cotton) materials as carrier and delivery agents for pseudoscent chemicals mimicking cocaine and methamphetamine. Through liquid chromatography-based analysis, both materials demonstrate capabilities to act as inert absorbents for the scent mimics, with cotton being the more effective material. Cotton material provides a safe, durable and inexpensive medium for pseudoscent storage and release. The pseudoscent delivery systems are easy to formulate, store and distribute, thus enabling widespread use for both specialised training and public educational purposes.
