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

backgroundAbout 655 million persons worldwide are affected by osteoarthritis (OA). As no therapy modifies disease progression long-term, there is an immense clinical need for novel therapies. The joints are innervated by alpha calcitonin gene-related peptide (αCGRP)- and substance P (SP)-positive sensory nerve fibers. Both neuropeptides have trophic effects on target cells within the joints. The aim of this study was to examine the effects of SP- and αCGRP-expressing intra-articular (i.a.) applied rat(r)BMSC on cartilage and subchondral bone structural changes after OA induction.

methodsMice were subjected to destabilization of the medial meniscus (DMM) surgery, followed by i.a. injections with rBMSC, transduced with lacZ, SP or αCGRP. 2, 8 and 16 weeks after DMM/Sham surgery, motion analysis and serum marker analysis were performed. Cartilage and subchondral bone properties were assessed by OA scoring, atomic force microscopy and nano-CT analysis.

resultsOARSI scores of the medial cartilage compartments indicated induction and progression of OA after DMM surgery in all groups. Differences between the treatment groups were mostly restricted to the lateral cartilage compartments, where αCGRP caused a decrease of structural changes. DMM-rBMSC-αCGRP or -SP mice displayed decreased cartilage stiffness in the cartilage middle zone. DMM-rBMSC-αCGRP mice revealed improved mobility, whereas Sham-rBMSC-SP mice revealed reduced mobility compared to rBMSC-lacZ. With respect to condyle length, subarticular bone and ephiphyseal bone morphology, DMM-rBMSC-SP mice had more alterations indicating either a more progressed OA stage or a more severe OA pathology compared to controls. In addition, DMM-rBMSC-SP mice developed osteophytes already 8 weeks after surgery. Adiponectin serum level was increased in DMM-rBMSC-αCGRP mice, and MIP1b level in DMM-rBMSC-SP mice. Notably, pain and inflammation markers increased over time in rBMSC-SP mice while rBMSC-αCGRP mice revealed a bell-shaped curve with a peak at 8 weeks.

conclusionsWe conclude that i.a. injection of rBMSC in general have a beneficial effect on cartilage matrix structure, subchondral bone microarchitecture and inflammation. rBMSC-αCGRP have anabolic and possible analgesic properties and may attenuate the progression or severity of OA. In contrast, rBMSC-SP exert a more catabolic influence on knee joints of both, Sham and DMM mice, making it a potential candidate for inhibition studies.
