Effects of recombinant human type I pancreatic elastase on human atherosclerotic arteries.
Article in Journal of cardiovascular pharmacology, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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.
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
rationaleAt physiologic pressures, elastic fibers constrain artery diameter. Local treatment of atherosclerotic arteries with PRT-201, a recombinant type I elastase, could result in fragmentation and removal of elastin fibers and increased vessel diameter.
objectiveTo investigate the use of PRT-201 as a treatment for human atherosclerotic arteries. METHODS AND
resultsArteries were harvested from donor legs amputated due to severe peripheral artery disease or from recently deceased persons who donated their bodies to science. Three- to four-centimeter artery segments were studied on a perfusion myograph to obtain baseline diameter data. After treatment with PRT-201 3.6 mg/mL or saline for 30 minutes myography was repeated. PRT-201 treatment resulted in an increase in vessel diameter across a range of transmural pressures. Average anterior tibial artery diameter increased by 0.78 ± 0.21 mm (27% ± 12%), whereas average posterior tibial artery diameter increased by 0.58 ± 0.30 mm (21% ± 11%), both P < 0.001. Elastin content as measured by desmosine radioimmunoassay was reduced by approximately 50%, P < 0.001.
conclusionsThe results suggest that PRT-201 treatment of atherosclerotic peripheral arteries in patients could increase artery diameter, and thus luminal area, possibly alleviating some of the symptoms of peripheral artery disease.
