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

Multinucleated cells termed chondroclasts have been observed on the deep surface of resorbed hyaline cartilage but the relationship of these cells to macrophages and osteoclasts and their role in rheumatoid arthritis (RA) and other arthritic conditions is uncertain. Multinucleated cells in RA and other arthritic conditions showing evidence of cartilage resorption were characterised immunohistochemically for expression of macrophage/osteoclast markers. Mature human osteoclasts formed from circulating monocytes and tissue macrophages were cultured for up to 4 days on slices of human cartilage and glycosaminoglycan (GAG) release was measured. Multinucleated cells resorbing unmineralised cartilage were seen in osteoarthritis, RA, septic arthritis, avascular necrosis and in four cases of giant cell tumour of bone that had extended through the subchondral bone plate. Chondroclasts expressed an osteoclast-like phenotype (TRAP+, cathepsin K+, MMP9+, CD14-, HLA-DR-, CD45+, CD51+ and CD68+). Both macrophages and osteoclasts cultured on cartilage released GAG. These findings indicate that chondroclasts have an osteoclast-like phenotype and that mature human osteoclasts are capable of cartilage matrix resorption. Resorption of unmineralised subchondral cartilage by chondroclasts and macrophages can be a feature of joint destruction in inflammatory and non-inflammatory arthropathies as well as inflammatory and neoplastic subchondral bone lesions.
