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

Opioids are a group of analgesic agents commonly used in clinical practice. The three classical opioid receptors are MOP, DOP and KOP. The NOP (N/OFQ) receptor is considered to be a non-opioid branch of the opioid receptor family. Opioid receptors are G-protein-coupled receptors which cause cellular hyperpolarisation when bound to opioid agonists. Opioids may be classified according to their mode of synthesis into alkaloids, semi-synthetic and synthetic compounds. Opioid use disorder (OUD) is an emerging issue and important lessons can be learnt from the United States where opioid epidemic was declared as a national emergency in 2017.
