1 · What the graph read from 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.

2 · The registry

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

introductionThe expression of matrix metalloproteinase-9 (MMP-9), MMP-13, and tissue inhibitor of metalloproteinases (TIMP-1) in head and neck squamous cell carcinoma (HNSCC) could be a useful predictor of tumour differentiation, nodal metastasis, and invasiveness. We conducted this study to ascertain the correlation between the expression of these markers and differentiation of tumour cells. MATERIALS AND

methodsA prospective observational study was conducted in a tertiary care center. Forty-three cases of proven HNSCC were recruited after obtaining informed consent. Using the surgically excised specimen, tumour differentiation and invasiveness were assessed and correlated with rates of expression of the markers. Chi-square test was done to correlate immunohistochemical (IHC) marker positivity and the degree of differentiation of the tumour, lymph node metastasis, and invasiveness.

resultsMMP-9, MMP-13, and TIMP-1 were expressed in 72%, 34%, and 18% of cases, respectively. p16 expression was not found in any of the cases. MMP-13 expression correlated with poorer differentiation of the tumour ( DISCUSSION: In our study, MMP-13 expression correlated with poorer tumour differentiation and younger age at diagnosis, giving indirect evidence of tumour aggressiveness. IHC markers can provide additional information to prognosticate HNSCC. Identifying potential targets for newer biological therapy is essential in the Indian population as there are biological differences in cancer behavior. Increased expression of the proteolytic MMP-13 correlated with poorer differentiation of HNSCC.
