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

purposeRecombinant apyrase (AZD3366) increases adenosine production and ticagrelor inhibits adenosine reuptake. We investigated whether intravenous AZD3366 before reperfusion reduces myocardial infarct size (IS) and whether AZD3366 and ticagrelor have additive effects.

methodsSprague-Dawley rats underwent 30 min ischemia. At 25 min of ischemia, animals received intravenous AZD3366 or vehicle. Additional animals received intravenous CGS15943 (an adenosine receptor blocker) or intraperitoneal ticagrelor. At 24 h reperfusion, IS was assessed by triphenyltetrazolium chloride. Other rats were subjected to 30 min ischemia followed by 1 h or 24 h reperfusion. Myocardial samples were assessed for adenosine levels, RT-PCR, and immunoblotting.

resultsAZD3366 and ticagrelor reduced IS. The protective effect was blocked by CGS15943. The effect of AZD3366 + ticagrelor was significantly greater than AZD3366. One hour after infarction, myocardial adenosine levels significantly increased with AZD3366, but not with ticagrelor. In contrast, 24 h after infarction, adenosine levels were equally increased by AZD3366 and ticagrelor, and levels were higher in the AZD3366 + ticagrelor group. One hour after reperfusion, AZD3366 and ticagrelor equally attenuated the increase in interleukin-15 (an early inflammatory marker after ischemic cell death) levels, and their combined effects were additive. AZD3366, but not ticagrelor, significantly attenuated the increase in RIP1, RIP3, and P-MLKL (markers of necroptosis) 1 h after reperfusion. AZD3366, but not ticagrelor, significantly attenuated the increase in IL-6 and GSDMD-N (markers of pyroptosis) 1 h after reperfusion. At 24 h of reperfusion, both agents equally attenuated the increase in these markers, and their effects were additive.

conclusionsAZD3366 attenuated inflammation, necrosis, necroptosis, and pyroptosis and limited IS. The effects of AZD3366 and ticagrelor were additive.
