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

BACKGROUND/

aimDegradation of the basement membrane and extracellular matrix by matrix metalloproteinases (MMPs) is believed to be an essential step in the complicated process of hematogenous metastasis. Matrix metalloproteinase-7 (MMP-7) is a small secreted proteolytic enzyme with a broad substrate specificity, and its expression has been shown to be associated with tumor invasion and metastasis for various cancers. PATIENTS AND

methodsTo document the role of MMP-7 polymorphism in esophageal carcinogenesis, a case-control study was performed comprising 135 patients with esophageal cancer (EC) and 195 healthy controls. Genotyping was done by the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. Data were statistically analyzed using χ2 - test and logistic regression models.

resultsCarriers for the MMP-7 (-181A>G) GG were associated with an increased risk for EC [odds ratio (OR = 2.17; 95% confidence interval (CI) = 1.21-3.92; P = 0.010; P-trend = 0.04]. Also, in a recessive model, our results showed that MMP-7 (-181A>G) GG allele conferred significantly higher risk for EC (OR =2.16; 95% CI = 1.31-3.54; P = 0.003). The high risk due to MMP-7 (-181GG) genotype was limited to squamous cell histology of EC (OR = 2.41; 95% CI = 1.27-4.56; P = 0.007). Although smoking (Hukka) and high consumption of salted tea are independent risk factors for EC, the interaction of MMP-7 (-181A>G) genotypes with these factors did not further modulate the risk of EC.

conclusionsIn conclusion, our results show that MMP-7 (-181A>G) GG carriers are at a higher risk of esophageal squamous cell carcinoma in Kashmir valley.
