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

backgroundAirway remodelling is a characteristic feature of chronic asthma and there is evidence that an airway imbalance between levels of matrix metalloproteinase-9 (MMP-9) and tissue inhibitor of metalloproteinases-1 (TIMP-1) is associated with airway remodelling. On this basis, we hypothesised that polymorphisms in the MMP-9 and TIMP-1 genes were associated with the disease process.

methodsA number of MMP-9 and TIMP-1 gene polymorphisms were examined in an adult white Australian population of mild (n = 259), moderate (n = 213) and severe (n = 71) asthmatics and non-asthmatic controls (n = 406) using PCR-RFLP and PCR-SSCP analyses.

resultsMMP-9 -1562C>T and 836G>A (Arg279Gln) were not associated with asthma (p> or =0.15) or asthma severity (p> or =0.13), and TIMP-1 434T>C (Phe124Phe) was not associated with asthma in women (p = 0.094) or men (p = 0.207). In this population, MMP-9 -861C>T and TIMP-1 323C>T (Pro87Pro) were not informative (with minor allele frequencies of <1%), and MMP-9 -1702T>A and TIMP-1 595C>T (Ser178Phe) were not detectable. However, a novel polymorphism was detected in the TIMP-1 gene 536C>T (Ile158Ile) which was significantly associated with asthma in women (p = 0.011; OR = 5.54, 95% CI 1.66 to 34.4) but not in men (p = 1.0). 536C>T was found to be in linkage disequilibrium with 434T>C, and haplotype analysis supported an association with asthma (p = 0.014).

conclusionsThis is the first reported association between a polymorphism in the TIMP-1 gene and asthma, and supports the hypothesis that the protease/antiprotease balance has an important role in this common disease.
