Immunohistochemical expression of MMP-2 and MMP-8 in oral squamous cell carcinoma.
Article in Journal of clinical and experimental dentistry, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 papers, 1 of them a synthesis that pooled 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.
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 metalloproteinases (MMPs) are endopeptidases that can degrade extracellular matrix components and affect invasiveness and aggressiveness of oral squamous cell carcinoma (OSCC). The aim of this study was to examine the immunohistochemical expression of MMP-2 and MMP-8 in OSCCs in patients presenting at the Tertiary Health facility in Nigeria. MATERIAL AND
methodsFormalin-fixed, paraffin-embedded (FFPE) OSCC samples diagnosed between the years 2010 and 2012 were used for his study. The FFPE were processed for MMP-2 and MMP-8 using the specifications of the manufacturer. Two investigators reviewed the slides scoring the pattern and intensity of staining as negative (0), weakly positive (+1), moderately positive (+2) and strongly positive (+3). The data were analysed using version 20 of the SPSS. The level of significance was set at P < 0.05.
resultsTwenty-five OSCC consisting of 14 (56%) males and 11 females (44%) were used. The mean age was 54.6 ± 17.9 years. A higher proportion (100%) of poorly differentiated OSCC strongly expressed MMP-2 compared with the well differentiated and moderately differentiated OSSC. There was no significant difference in the expression of MMP-2 amongst the three grades of OSCC (X2 = 2.87; p= 0.17). Only 5 (20%) OSCC cases positively expressed MMP-8. Moderate expression of MMP-8 was only seen in well-differentiated OSCCs.
conclusionsThis study showed that a higher proportion of poorly differentiated OSSC strongly expressed MMP-2. Eighty percent of cases that express MMP-8 were females and moderate expression of MMP-8 was seen only in well differentiated OSCC. Key words:Oral squamous cell carcinoma, MMP-2, MMP-8, immunohistochemistry.
