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

introductionInsulin has shown antioxidation and cytoprotective effects to decrease heart ischemia/reperfusion injury (HI/RI) in diabetes mellitus (DM), but the role of insulin/poly(ethylene glycol)-carboxymethyl chitosan (PEG-CMCS) on HI/RI in DM is not known. This research explored whether insulin/PEG-CMCS revealed a protective effect on HI/RI in DM through ornithine decarboxylase (ODC)/polyamine systems. MATERIALS AND

methodsDiabetes was induced via streptozotocin (STZ) in Sprague Dawley (SD) rats, which suffered from HI via blocking the left circumflex artery for 45 minutes, followed by 2 hours of reperfusion. α-Difluoromethylornithine-ethylglyoxal bis (guanylhydrazone) (DFMO-EGBG) and insulin/PEG-CMCS were administered to diabetic rats to explore their roles on severity of HI/RI.

resultsInsulin could be fleetly and efficiently loaded via the nanocarrier PEG-CMCS at pH =6, showing efficient loading and stable release. In addition, insulin/PEG-CMCS showed significant hypoglycemic activity in diabetic rats. On the other hand, ischemia/reperfusion obviously augmented the contents of creatine kinase (CK), lactic dehydrogenase (LDH), putrescine (Pu), myocardial infarct size, and NF-κB and spermidine/spermine N'-acetyltransferase (SSAT) expressions and decreased the levels of spermine (Sp), polyamine pools (PAs), heart rate (HR), coronary blood flow (CF), left ventricular developed pressure (LVDP), and ODC expression, compared with Sham. Administration of insulin and insulin/PEG-CMCS both reduced the contents of CK, LDH, Pu, myocardial infarct size, and NF-κB and SSAT expressions and increased the levels of Sp, PAs, HR, CF, LVDP, and ODC expression, while insulin/PEG-CMCS significantly indicated the protective results, and DFMO-EGBG showed the opposite effects.

conclusionThe research showed that insulin/PEG-CMCS could play a protective effect on HR/RI in diabetic rats via its antioxidative, antiapoptotic, and anti-inflammatory roles and modulating ODC/polyamine systems.
