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

Women are disproportionately affected by chronic pain compared with men. While societal and environmental factors contribute to this disparity, sex-based biological differences in the processing of pain are also believed to play significant roles. The central lateral nucleus of the amygdala (CeLC) is a key region for the emotional-affective dimension of pain, and a prime target for exploring sex differences in pain processing since a recent study demonstrated sex differences in CGRP actions in this region. Inputs to CeLC from the parabrachial nucleus (PB) play a causal role in aversive processing and release both glutamate and calcitonin gene-related peptide (CGRP). CGRP is thought to play a crucial role in chronic pain by potentiating glutamatergic signaling in CeLC. However, it is not known if this CGRP-mediated synaptic plasticity occurs similarly in males and females. Here, we tested the hypothesis that female CeLC neurons experience greater potentiation of glutamatergic signaling than males following endogenous CGRP exposure. Using trains of optical stimuli to evoke transient CGRP release from PB terminals in CeLC, we find that subsequent glutamatergic responses are preferentially potentiated in CeLC neurons from female mice. This potentiation was CGRP dependent and involved a postsynaptic mechanism. This sex difference in CGRP sensitivity may explain sex differences in affective pain processing.
