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

purposeWe evaluated a dimeric RGD-peptide, [(68)Ga]DOTA-E-[c(RGDfK)]2, for positron emission tomography (PET) imaging of myocardial integrin expression associated with extracellular matrix remodeling after myocardial infarction (MI) in rat. PROCEDURES: Male Sprague-Dawley rats were studied at 7 days and 4 weeks after MI induced by permanent ligation of the left coronary artery and compared with sham-operated controls.

resultsIn vivo imaging revealed higher tracer uptake in the infarcted area than in the remote non-infarcted myocardium of the same rats both at 7 days (MI/remote ratio, 2.25 ± 0.24) and 4 weeks (MI/remote ratio, 2.13 ± 0.37) post-MI. Compared with sham-operated rats, tracer uptake was higher also in the remote, non-infarcted myocardium of MI rats both at 7 days and 4 weeks where it coincided with an increased interstitial fibrosis. Standardized uptake values correlated well with the results of tracer kinetic modeling. Autoradiography confirmed the imaging results showing 5.1 times higher tracer uptake in the infarcted than remote area. Tracer uptake correlated with the amount of β3 integrin subunits in the infarcted area.

conclusionsOur results show that integrin-targeting [(68)Ga]DOTA-E-[c(RGDfK)]2 is a potential tracer for monitoring of myocardial extracellular matrix remodeling after MI using PET.
