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

objectiveTo investigate whether the enhancement of joint lymphangiogenesis by injection of vascular endothelial growth factor C (VEGF-C) adeno-associated virus (AAV) into the affected joints has therapeutic efficacy in chronic inflammatory arthritis in mice.

methodsTumor necrosis factor-transgenic (TNF-Tg) mice were used as a model of chronic inflammatory arthritis. Human VEGF-C was cloned into an AAV expression vector to generate AAV-VEGF-C. The joints of TNF-Tg mice were injected with AAV-VEGF-C or AAV-luciferase (AAV-Luc) as a control. During the 4 months following injection, magnetic resonance imaging of the joints and lymphatic imaging were performed to assess changes in synovial volume and lymph flow from the joint tissues to local draining lymph nodes. Joint inflammation, bone erosion, and cartilage loss were examined by histologic analyses. Lymphatic vessel formation was assessed using immunohistochemistry.

resultsIntraarticular administration of AAV-VEGF-C virus significantly attenuated the increase in synovial volume and increased lymphatic vessel number in the joint sections, as compared with that in control AAV-Luc-injected joints, during the 4-month period. This was accompanied by a reduction in the area of inflammation, bone erosion, cartilage loss, and osteoclast numbers. Lymph flow from the joints to local draining lymph nodes was slower in TNF-Tg mice than in wild-type littermates, and was significantly improved with AAV-VEGF-C treatment.

conclusionIntraarticular injection of AAV-VEGF-C increased lymphangiogenesis and improved lymphatic drainage from the inflamed joints of mice, resulting in attenuation of joint tissue damage. Thus, improvement of joint lymphatic function by local administration of lymphatic growth factors represents a new therapeutic approach for chronic inflammatory arthritis.
