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

Doxorubicin-induced cardiomyopathy (DOX-IC) is a significant and common complication in patients undergoing chemotherapy, leading to cardiac remodeling and reduced heart function. We hypothesized that the intrapericardial injection of hydrogels derived from the cardiac decellularized extracellular matrix (dECM) loaded with adipose tissue-derived stromal cells (ASC) and their secretome dampens or reverses the progression of DOX-IC. DOX-IC was induced in Wistar male rats through ten weekly intra-peritoneal injections of doxorubicin (cumulative dose: 18 mg/kg). We performed intrapericardial treatment in week five with dECM hydrogel loaded with ASC and their conditioned medium (CMed). The volume of intrapericardial injection was 2 ml/kg, the ASC density was 20 million/mL, while the hydrogel contained 100-fold concentrated CMed. Interstitial myocardial fibrosis was assessed by PicroSirius Red staining and hemodynamics parameters in pressure-volume loops. Compared to saline controls, interstitial myocardial fibrosis was reduced in ASC/CMed-loaded hydrogels treated animals (p = 0.0139). Ejection fraction and cardiac work efficiency improved in the ASC/CMed-treated rats compared to saline treatment (p = 0.0151 and p = 0.0655, respectively). The intrapericardial injection of dECM hydrogels loaded with ASC and their secretome warrants a novel therapeutic modality to improve ventricular hemodynamics and reduce cardiac remodeling in DOX-IC.
