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

aimsChronic pain management remains a major clinical challenge due to the limited availability of effective therapies that avoid severe side effects. The rostral ventromedial medulla (RVM) is a critical brainstem center for pain modulation; however, the neurochemical identity and functional roles of its neuronal subpopulations remain incompletely understood.

methodsWe performed a series of tests by constructing a complete Freund's adjuvant (CFA)-induced inflammatory nociceptive model and a chronic constrictive injury (CCI) neuropathic pain model combined with behavioral experiments, in situ hybridization, chemogenetics, optogenetics, and in vivo electrophysiological techniques.

resultsThis study identifies enkephalinergic neurons in the RVM and their projections to the subnucleus reticularis dorsalis (SRD) as a distinct descending pain-inhibitory circuit. RNAscope shows elevated ENK

conclusionThese findings identify the ENK
