Increased level of phosphorylated desmin and its degradation products in heart failure.
Article in Biochemistry and biophysics reports, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 15 papers.
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
Although several risk factors such as infarct size have been identified, the progression/severity of heart failure (HF) remains difficult to predict in clinical practice. Using an experimental rat model of ischemic HF and phosphoproteomic technology, we found an increased level of phosphorylated desmin in the left ventricle (LV) of HF-rats. The purpose of the present work is to assess whether desmin is a circulating or only a tissue biomarker of HF. We used several antibodies in order to detect desmin, its proteolytic fragments and its phosphorylated form in LV and plasma by western blot, phosphate affinity electrophoresis, mass spectrometry and immunofluorescence. Plasma was treated with combinatorial peptide ligand library or depleted for albumin and immunoglobulins to increase the sensitivity of detection. We found a 2-fold increased serine-desmin phosphorylation in the LV of HF-rats, mainly in the insoluble fraction, suggesting the formation of desmin aggregates. Desmin cleavage products were also detected in the LV of HF rats, indicating that the increased phosphorylation of desmin results in more susceptibility to proteolytic activity, likely mediated by calpain activity. The native desmin and its degradation products were undetectable in the plasma of rat, mouse or human. These data suggest the potential of serine-phosphorylated form of desmin and its degradation products, but not of desmin itself, as tissue but not circulating biomarkers of HF.
