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

backgroundAlthough opioids suppressive effects on immune system function have been reported, this study demonstrates inflammatory reactions, such as production of pro-inflammatory cytokines and suppression of anti-inflammatory cytokines, are the main causes at organ's allotransplantation rejection in chronic morphine-treated recipients.

methods28 rats were categorized in 4 groups through intra-peritoneal administrations: control, sham, morphine treated animals (20 mg/kg injected of morphine daily until biopsy day), morphine and naloxane treated animals (20 mg/kg morphine and 2mg/kg naloxane daily injected until biopsy day), which their donors were normal rats. The grafts were done at the 14th day of the experiment. Plasma interleukins levels (IL-6 and IL-10) in three sampling times were measured by ELISA. With almost 80% of macroscopic rejection signs in rats of one group, full thickness skin biopsy has been taken and histological parameters like perivascular infiltrates, epidermal changes, and stromal changes were detected. The statistical significance differences between the control and experimental groups were analyzed using the Kruskal-Wallis, followed by ANOVA post hoc test.

resultsAccelerated skin allograft rejection by chronic morphine consumption can be resulted of increased IL-6 concentration and decreased IL-10. The enhancing effects of morphine on the graft inflammation were partially antagonized by Naloxane. It can illustrate the complexity of opiates and immune system connections and should be considered during organ transplantation of opiate addicts.

conclusionExpansion of skin cells in recipient with chronic morphine administration history may be resulted in failure.
