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 interleukin 13 (IL13) could act in a chondroprotective manner and protect cartilage stimulated to resorb with a combination of IL1alpha and oncostatin M (OSM), in a similar way to the anti-inflammatory cytokine, IL4.

methodsIL13 was added to explant cultures of bovine nasal cartilage stimulated to resorb with IL1alpha and OSM, and the release of collagen and proteoglycan determined. Collagenolytic and tissue inhibitors of metalloproteinase (TIMP) activities were determined by bioassay. Northern blot analyses were performed to determine the effects of IL13 on the induction of matrix metalloproteinase-1 (MMP-1), MMP-3, MMP-13, and TIMP-1 gene expression.

resultsIL13 can prevent the release of collagen from bovine nasal cartilage in a dose dependent manner. This was accompanied by a concomitant decrease in measurable collagenolytic activity in the culture supernates and an increase in TIMP activity. Northern blot analysis showed that IL13 down regulated MMP-3 and MMP-13 levels but up regulated MMP-1 and TIMP-1 gene expression in bovine nasal chondrocytes at 24 hours.

conclusionThis study showed for the first time that IL13 can block collagen release from resorbing cartilage in a similar manner to IL4. This is accompanied by a reduction in detectable collagenolytic activity, a decrease in MMP-3 and MMP-13 mRNA levels, and an up regulation of TIMP-1 expression.
