Correlation between MMP2 expression in lung cancer tissues and clinical parameters: a retrospective clinical analysis.
Article in BMC pulmonary medicine, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 42 papers.
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
backgroundMatrix metalloproteinase 2 (MMP2) has been found to be related to malignant tumors; the aim of this study was to investigate the correlation between MMP2 expression in lung cancer tissues and clinical parameters of lung cancer.
methodsThe expression of MMP2 in lung cancer tissues and in adjacent non-malignant tissues was tested by immunohistochemistry. The correlation between the expression of MMP2 and clinical parameters of lung cancer was analyzed by Kaplan-Meier curve and multiple regression analysis.
resultsThe expression of MMP2 was higher in lung cancer tissues than that in adjacent non-malignant tissues (p = 0.002). Increased MMP2 was associated with low differentiation (p = 0.022), tumor size (p = 0.032), lymph node metastasis (p < 0.001), advanced stage (p = 0.002). The post-surgical survival time in patients with high MMP2 expression was shorter than that in patients with low MMP2 expression (p = 0.001). High expression of MMP2 (p = 0.006) and advanced stage (p = 0.003) were independent prognostic indicators for survival of lung cancer patients.
conclusionsIncreased MMP2 correlates with malignant biological behavior of lung cancer and it could be a potential biomarker for diagnosis and prognosis of the disease.
