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

objectivesButorphanol tartrate is a synthetic opioid partial agonist analgesic. Butorphanol targets the heart, mainly via κ-opioid receptor (κ-OR) activation. The purpose of this study was to determine the effect and mechanism underlying butorphanol postconditioning (B-Post) on myocardial ischaemia reperfusion injury in rats.

methodsSeventy-five male Sprague-Dawley rats were randomly divided into five groups of 15 each: Group sham; Group I/R (ischaemia/reperfusion); Group B (butorphanol postconditioning); Group B/N (butorphanol postconditioning + antagonist of κ-OR nor-binaltorphimine [Nor-BNI]); Group B/G (butorphanol postconditioning + nonselective ATP-sensitive potassium (KATP) channel blocker glibenclamide [GLI]). The left coronary anterior descending artery (LAD) was occluded for 30 min, followed by a 120-min reperfusion. Blood samples were obtained at the end of reperfusion for determination of serum tumour necrosis factor (TNF)-α and interleukin (IL)-6 concentrations. The hearts were then excised for determination of myocardial infarct size by triphenyltetrazolium chloride staining. The myocardial tissues were used for determination of the expression of myocardial superoxide dismutase (SOD), malondialdehyde (MDA) and myeloperoxidase (MPO).

resultsMyocardial infarct size was significantly reduced in B (26.4 ± 1.83%), B/N (34.5 ± 1.56%) and B/G (31.5 ± 1.27%) Groups compared with Group I/R (46.8 ± 1.41%) (all P < 0. 001). The serum TNF-α and IL-6 concentrations and the MDA and MPO activities in the ischaemic area in B, B/N and B/G Groups were significantly lower than those in the I/R Group (all P < 0.001). In addition, myocardial infarct size, TNF-α and IL-6 concentrations and the MDA and MPO activities in B/N and B/G Groups were higher than those in the B Group (all P < 0.001). In contrast, SOD activity was significantly increased in B, B/N and B/G Groups, and SOD activity in B/N and B/G Groups was less than in the B Group (all P < 0.001).

conclusionsThese results suggest that postconditioning of butorphanol tartrate can provide a potent cardioprotective effect against myocardial ischaemic and reperfusion injury. Both the κ-OR and the KATP channels were involved in this effect.
