MMP-2 (-1306 C/T) Polymorphism Affects Serum Matrix Metalloproteinase (MMP)-2 Levels and Correlates with Chronic Obstructive Pulmonary Disease Severity: A Case-Control Study of MMP-1 and -2 in a Tunisian Population.

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.
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
objectiveThe aim of this study was to determine the role of MMP-1 (-1607 1G/2G; -519 A/G) and MMP-2 (-1306 C/T; -735 C/T) polymorphisms in the development and severity of chronic obstructive pulmonary disease (COPD) in Tunisian patients. We also evaluated the impact of these genetic variants on serum levels of the corresponding proteins.
methodsThe study included 138 patients with COPD and 216 healthy controls. Pulmonary function was evaluated using body plethysmography, and COPD severity was determined based on forced expiratory volume in 1 s (FEV1%). MMP-1 and MMP-2 variants were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP), while serum matrix metalloproteinase (MMP)-1 and -2 levels were determined by enzyme-linked immunosorbent assay (ELISA) and activity of MMP-2 was determined by gelatin zymography.
resultsNo significant associations were found between genetic variations in MMP-1 and MMP-2 variants and the risk of development of COPD. Additionally, no significant impact of the MMP-1 (-1607 1G/2G; -519 A/G) and MMP-2 (-735 C/T) polymorphisms was observed on the respective protein levels and clinical parameters of the disease. Interestingly, a significant correlation was identified between the MMP-2 (-1306) C/T and disease severity [p = 0.01; Bonferroni corrected p value (p
conclusionOur data suggest that, although MMP-1 (-1607 1G/2G; -519 A/G) and MMP-2 (-735 C/T) may not affect COPD risk and clinical parameters, the MMP-2 (-1306C/T) variant was correlated to COPD severity. These findings could be related to alterations in the level and activity of MMP-2 in serum from patients carrying the (-1306) CC genotype.
