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

Osteoarthritis (OA) is a progressive degenerative disease of the joints caused in part by a change in the phenotype of resident chondrocytes within affected joints. This altered phenotype, often termed proinflammatory or procatabolic, features enhanced production of endoproteinases and matrix metallo-proteinases (MMPs) as well as secretion of endogenous inflammatory mediators. Degradation and reduced retention of the proteoglycan aggrecan is an early event in OA. Enhanced turnover of hyaluronan (HA) is closely associated with changes in aggrecan. Here, to determine whether experimentally increased HA production promotes aggrecan retention and generates a positive feedback response, we overexpressed HA synthase-2 (HAS2) in chondrocytes via an inducible adenovirus construct (HA synthase-2 viral overexpression; HAS2-OE). HAS2-OE incrementally increased high-molecular-mass HA >100-fold within the cell-associated and growth medium pools. More importantly, our results indicated that the HAS2-OE expression system inhibits MMP3, MMP13, and other markers of the procatabolic phenotype (such as TNF-stimulated gene 6 protein (TSG6)) and also enhances aggrecan retention. These markers were inhibited in OA-associated chondrocytes and in chondrocytes activated by interleukin-1β (IL1β), but also chondrocytes activated by lipopolysaccharide (LPS), tumor necrosis factor α (TNFα), or HA oligosaccharides. However, the enhanced extracellular HA resulting from HAS2-OE did not reduce the procatabolic phenotype of neighboring nontransduced chondrocytes as we had expected. Rather, HA-mediated inhibition of the phenotype occurred only in transduced cells. In addition, high HA biosynthesis rates, especially in transduced procatabolic chondrocytes, resulted in marked changes in chondrocyte dependence on glycolysis
