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

The expression of vascular endothelial growth factor (VEGF) directly correlates with the Mankin score and the degree of cartilage destruction. The biological activity of VEGF on articular cartilage remains unknown, so this study was performed to investigate the effect of VEGF on aggrecan and type II collagen expression in vitro. We carried out this study at the Center Laboratory of Renmin Hospital at Wuhan University. Rat articular chondrocytes were cultured in a monolayer. Then, the experiment was divided into 4 groups: group A (control group), without any disposal; group B, treated with 10 ng/ml VEGF; group C, treated with 10 ng/ml IL-1β; and group D, treated with 10 ng/ml VEGF + 10 ng/ml IL-1β. After 48 h, messenger RNA (mRNA) expression of aggrecan and type II collagen was evaluated by real-time polymerase chain reaction (real-Time PCR), and protein expression of aggrecan and type II collagen was detected by Western blotting. VEGF was found to significantly inhibit the expression of aggrecan and type II collagen at the gene and protein levels. These findings suggest that VEGF may result in degeneration of articular cartilage by inhibiting the synthesis and expression of aggrecan and type II collagen.
