Relationship between matrix metalloproteinase-9 and some clinicopathological prognostic factors of breast carcinoma.
Article in American journal of clinical and experimental immunology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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-9 (MMP-9), an enzyme with major role in remodeling of extracellular matrix, has been the focus of attention in some previous studies in the field of breast cancer. In the current study the relationship between matrix metalloproteinase-9 and some clinicopathological factors of breast carcinoma has also been evaluated.
methodsFormalin-fixed and paraffin-embedded tissue specimens from three groups including 40 invasive breast carcinoma (tumor group) and their adjacent normal tissue (tumor control), as well as 40 normal mammoplasty specimens (normal control) were studied. The samples were from the pathology archive of Alzahra Hospital, Isfahan, Iran, from 2016 to 2018. The status of intraepithelial MMP-9 were studied and compared in these three groups using immunohistochemistry.
resultsThe extent of intraepithelial MMP-9 immunostaining in all positive specimens was 100%. The results of intraepithelial MMP-9 staining intensity was as follow: 12.5% strong, 27.5% moderate, 27.5% mild, and 32.5% negative in tumor group; 17.5% strong, 22.5% moderate, 32.5% mild, and 27.5% negative in tumor control group; and 10% strong, 40% moderate, 27.5% mild, and 22.5% negative in normal control group. Intraepithelial MMP-9 immunostaining intensity showed significant difference between tumor and tumor control groups (P<0.001). Intraepithelial MMP-9 immunostaining intensity showed no significant difference between tumor and normal control groups, and between tumor control and normal control groups (P>0.05). No significant relationship was seen between intraepithelial MMP-9 immunostaining intensity and age, tumor size, tumor grade, and lymph node status in tumor group (P>0.05).
conclusionIntraepithelial MMP-9 expression increases in some breast carcinomas. Normal breast tissue adjacent to carcinoma does not show such increase. However, intraepithelial MMP-9 expression in breast carcinoma does not show any significant relationship with age, tumor size, tumor grade, and lymph node status.
