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

Cyclophosphamide (CP) is a nitrogen mustard alkylating agent with effective antineoplastic, immunomodulatory and immunosuppressive properties. Despite its vast therapeutic uses, it is known to trigger strict cardiac toxicity. The objective of the current study was to examine the protective role of metformin (MET) and/or low dose radiation (LDR) on cardiotoxicity and apoptosis induced by CP in rats. CP (200 mg/kg i.p) induces cardiotoxicity and apoptosis as indicated by elevation of troponin, cardiac caspase-3 and Endothelin-I (ET-1). While, treatment with MET (150 mg/kg, orally for 14 days) and/or LDR (0.5 Gy) before CP hindered CP-induced toxicity. By estimating the apoptotic index (BAX/Bcl-2 ratio) CP showed significantly the highest BAX/Bcl-2 ratio. Administration of MET and/or LDR showed a significant improvement in oxidative stress indices and reverse the inhibitory effect of CP on SIRT-1. Also, Histological examination of cardiac tissues showed a sign of necrosis of myocardium after CP treatment. Conclusions: The results revealed that MET and/or LDR attenuate CP-induced cardiotoxicity by inhibiting oxidative stress and preserving the activity of antioxidant enzymes through SIRT-1/SOD and BAX/Bcl-2 pathways.
