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

objectiveIschemic stroke (IS) results from interrupted blood flow to the brain and can be caused by formation of atherosclerotic plaques in blood vessels. Previous studies have suggested a contribution of matrix metalloproteinases (MMP) to plaque formation and stroke risk. Here, we explored associations between two MMPs, MMP-2 and MMP-9, and IS.

methodsThere were 396 IS patients and 400 control individuals involved in this study. The MMP-2 -1306C/T and -735C/T polymorphisms and MMP-9 -1562C/T polymorphism were analyzed by restriction fragment length polymorphism (RFLP) from patient blood samples, and the relationships to IS were analyzed by logistic regression.

resultsGenotype and allele frequencies of MMP-2 -1306C/T did not differ statistically (P>0.05), but those of MMP-2 -735C/T and MMP-9 1562C/T did differ between IS and control samples (P<0.05). While MMP-2 -1306C/T polymorphism was not associated with increased risk of IS, MMP-2 -735C allele was associated with a 1.5-fold increase in IS incidence (OR=1.516, 95% CI=1.185-1.940, P=0.001), and MMP-9 -1562T allele was associated with a 1.5-fold increase in IS incidence (OR=1.543, 95% CI=1.144-2.080, P=0.004).

conclusionMMP-2 -735C and MMP-9 -1562T may act as IS susceptibility alleles.
