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
Background: p53 tumour suppressor gene limits unchecked cellular growth in response to DNA damage, by causing G1 arrest and the activation of apoptosis. Inhibitors of apoptosis include survivin which acts by inhibition of caspases. Survivin has a significant role as a cell cycle modulator and is only minimally present in mature tissues. Aberrant expression of p53 and survivin has been evaluated in various carcinomas. Thus, the objective of this research was to elucidate the co-expression of p53 and survivin in tissue samples of Oral Potentially Malignant Disorders (OPMDs) and Oral Squamous Cell Carcinoma (OSCCs). Method: Thirty tissue samples of OPMDs and 30 tissue samples of OSCCs taken from department archives were used in the study. Expression of p53 and survivin was analyzed in the study groups by the help of immunohistochemistry. Also, co-expression of both the markers was evaluated. Results: The expression of p53 and survivin in the oral epithelium of patients with OSCCs was significantly higher than that in patients with OPMDs ( Conclusion: Our results provide insights into the altered survivin and p53 co-expression with significant immunoexpression within the study groups. Therefore, survivin and p53 could be better markers for identifying cell proliferation and apoptotic pathway. Also, malignant transformation rate of OPMD increases with increased expression of these markers.
