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

backgroundTissue engineering has exhibited great effect on treatment for bone-tendon interface (BTI) injury. The aim of this study was to evaluate the effect of a book-shaped acellular tendon scaffold (ATS) with bone marrow mesenchymal stem cells sheets (MSCS) for BTI injury repair.

methodsATS was designed based on the shape of "book", decellularization effect was evaluated by Hematoxylin and eosin (H&E), 4', 6-diamidino-2-phenylindole (DAPI) and scanning electron microscopy (SEM), then bone marrow mesenchymal stem cells (MSCs) were cultured on ATS to assess the differentiation inductivity of ATS. A rabbit right partial patellotomy model was established, and MSCS seeded on ATS were implanted into the lesion site. The patella-patellar tendon (PPT) at 2, 4, 8 or 16 weeks post-operation were obtained for histological, biomechanical and immunofluorescence analysis.

resultsH&E, DAPI and SEM results confirmed the efficiency of decellularization of ATS, and their in vitro tenogenic and chondrogenic ability were successfully identified. In vivo results showed increased macrophage polarization toward the M2 phenotype, IL-10 expression, regenerated bone and fibrocartilage at the patella-patellar tendon interface of animals received MSCS modified ATS implantation. In addition, the level of tensile strength was also the highest in MSCS modified ATS implantation group.

conclusionThis study suggests that ATS combined with MSCS performed therapeutic effects on promoting the regeneration of cartilage layer and enhancing the healing quality of patella-patellar tendon interface. THE TRANSLATIONAL POTENTIAL OF THIS ARTICLE: This study showed the good biocompatibility of the ATS, as well as the great efficacy of ATS with MSCS on tendon to bone healing. The results meant that the novel book-shaped ATS with MSCS may have a great potential for clinical application.
