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

While opioids produce both analgesia and side effects by action at μ-opioid receptors (MORs), at spinal and supraspinal sites, the potency of different opioids to produce these effects varies. While it has been suggested that these differences might be because of bias for signaling via β-arrestin versus G-protein α-subunits (Gα), recent studies suggest that G-protein-biased MOR agonists still produce clinically important side effects. Since bias also exists in the role of Gα subunits, we evaluated the role of Gα
