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

The anterior cingulate cortex (ACC) is implicated in many pathologies, including depression, anxiety, substance-use disorders, and pain. There is also evidence from brain imaging that the ACC is hyperactive during periods of opioid withdrawal. However, there are limited data contributing to our understanding of ACC function at the cellular level during opioid withdrawal. Here, we address this issue by performing ex vivo electrophysiological analysis of thick-tufted, putative dopamine D2 receptor expressing, layer V pyramidal neurons in the ACC (ACC L5 PyNs) in a mouse model of spontaneous opioid withdrawal. We found that escalating doses of morphine (20, 40, 60, 80, and 100 mg/kg, i.p. on days 1-5, respectively) injected twice daily into male C57BL/6 mice evoked withdrawal behaviors and an associated withdrawal-induced mechanical hypersensitivity. Brain slices prepared 24 h following the last morphine injection showed increases in ACC L5 thick-tufted PyN-intrinsic membrane excitability, increases in membrane resistance, reductions in the rheobase, and reductions in HCN channel-mediated currents (I
