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

Identifying how opioids modulate signaling in relevant neurocircuitry is essential for developing new therapeutic strategies for opioid addiction. The medial habenula (MHb) is a mu-opioid receptor (MOR) hotspot that projects predominantly to the interpeduncular nucleus (IPN); however, little is known about MOR function in this pathway. Using reporter mice, we observed MOR expression in a subset of MHb and IPN neurons, where its activation induces inhibitory effects on neuronal activity. However, stimulation of MOR
