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

Matrix metalloproteinases (MMPs) are involved in joint destruction in rheumatoid arthritis (RA), and are strongly associated with levels of inflammation. To understand the relationship between MMP-1 and -3 variants and MMP levels in RA, we investigated the genotypic and haplotypic relationships of the MMP-1 and -3 genes with circulating levels of these MMPs. The genotypes of single-nucleotide polymorphisms (SNPs) rs1799750 (1G/2G, MMP-1 promoter), rs495366 (G/A, intergene), rs679620 (A/G, MMP-3 coding region) and rs3025058 (5A/6A, MMP-3 promoter) were determined in 430 RA patients. Each polymorphism was associated with serum levels of MMP-1 (P trend <0.0001 for each SNP), with haplotype 1G-G-A-5A associated with the highest level. The intergenic and MMP-3 SNPs were associated with MMP-1 levels independent of the MMP-1 promoter SNP. The MMP-3 SNPs were associated with serum MMP-3 level (P trend <0.0001 for each SNP), and were each associated with mean time-averaged disease activity (DAS28) in patients followed up for 2 years (P=0.003). Our findings indicate that several closely linked polymorphisms in the MMP-1-MMP-3 loci have an important role in determining the circulating levels of these MMPs in RA, and that MMP-3 polymorphism is associated with the level of disease activity over time.
