The effect of progesteron for expression delta (δ) opioid receptor spinal cord through peripheral nerve injury.
Article in Annals of medicine and surgery (2012), 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
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
backgroundNeuropathic pain is a major problem to date because of its high prevalence and lack of effective treatment. Neuropathic pain processes can be influenced by many factors and at various levels of the nervous system, including progesterone and the opioid system. The various mechanisms of the effect of progesterone on pain are still controversial, while the effect of progesterone on the activation of the opioid system also needs to be proven. This study aimed to determine the effect of progesterone on pain through the modulation mechanism of the opioid system.
methodsThis research is a completely randomized experimental study using male wistar rats aged around three months at the Experimental Animal Laboratory, Department of Medical Biochemistry, Faculty of Medicine, Airlangga University.
resultsThe result was analyzed by using statistical analysis of two independent samples (
conclusionIt was shown that there was a significant difference in the delta (δ) opioid receptor expression between the control group and the progesterone group, which indicated that progesterone causes an increase in the delta (δ) opioid receptor expression in the spinal cord.
