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

Introduction: Growing evidence has shown that cyclooxygenase-2 (COX-2), an enzyme capable of catalyzing prostaglandin production, plays a key role in carcinogenesis. Selective COX-2 inhibitors have been shown to reduce the establishment of tumors such as oral squamous cell carcinoma (OSCC) and premalignant conditions such oral submucous fibrosis (OSMF) in experimental models. The aim of this study was to investigate the immunohistochemical expression of COX-2 in OSCC and OSMF with the normal oral mucosa as control. Material and Methods: Forty-five formalin-fixed paraffin-embedded samples comprising 20 OSCC, 20 OSMF, and 5 normal oral mucosa specimens were withdrawn from the archives of the Department of Oral and Maxillofacial Pathology for immunohistochemical examination for COX-2 expression. Negative and less than 5% COX-2 positivity was considered negative expressions, while greater than or equal to 5% COX-2 positivity was considered positive expression. The data obtained were statistically analyzed. Results: The difference in percentages of expression in normal mucosa, OSCC, and OSMF was highly significant ( Conclusion: The results of the present study confirm the role of COX-2 in carcinogenesis and in the progression of premalignant conditions to malignancy.
