Expression of matrix metalloproteinase (MMP)-2, MMP-9, and tissue inhibitor of MMP (TIMP)-1 in conjunctival melanomas and clinical implications.

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
purposeTo investigate the expression of matrix metalloproteinase (MMP)-2, MMP-9, and tissue inhibitor of matrix metalloproteinase (TIMP)-1 in conjunctival melanomas and their correlations with clinicopathologic parameters and prognosis.
methodsFourteen conjunctival melanoma tissue samples and nine conjunctival nevus tissue samples were stained immunohistochemically for MMP-2, MMP-9, and TIMP-1. Association of MMP-2, MMP-9, and TIMP-1 expression in melanoma tissues with clinical progression in terms of metastasis, recurrence, mitotic index, thickness, base diameter, and invasion depth was analyzed.
resultsIn the melanoma group, 78.6% of samples showed a positive reaction for MMP-2, 85.7% for MMP-9, and 100% for TIMP-1. In the nevus group, 11.1% showed a positive reaction for MMP-2, 66.7% for MMP-9, and 100% for TIMP-1. MMP-2 expression was significantly more induced in conjunctival melanoma than in benign nevi (P = 0.002). In conjunctival melanoma, MMP-9 expression was higher in tumors >1.5 mm thick (P = 0.026) and TIMP-1 expression was higher in recurrent cases (P = 0.03). There was no significant correlation between the expression and metastasis during the follow-up period (mean, 5 years).
conclusionMMP-2, MMP-9, and TIMP-1 were expressed in the majority of conjunctival melanomas, and MMP-2 might play a role in the development and clinical behavior of conjunctival melanoma.
